Optimization of the ion extraction from an inductively coupled plasma (ICP) by IBSimu modeling. Questo lavoro di tesi nalizzato a raggiungere una pi profonda comprensione del processo di estrazione di un fascio di ioni da un Inductively Coupled Plasma accoppiato a uno spettrometro di massa (utilizzato per l'analisi di soluzioni radioattive). Elizabethan Era Foods. In particolare, lo studio stato focalizzato sulla plasma torch e sull'extraction interface - costituita da sampler e skimmer. Per capire i processi che avvengono tra lo skimmer - a valle del quale il plasma perde la sua quasi-neutralit - e la prima lente ottica, stato utilizzato IBSimu, un software appositamente creato per simulare l'estrazione di ioni ed elettroni da una sorgente di plasma. As said in axolotl teeth, the previous section, nowadays one of the most important meth- ods in atomic spectrometry is the ICP-MS: the elizabethan era foods, two main reasons for its success are the true multi-element capabilities and the extremely low detec- tion limits. All ICP sector eld instruments consist of [41]: ' an ion source (see chapter 3 for a detailed description); ' a sampling interface (see chapter 4 for a detailed description); ' an electrostatic lens system, used to guide, focus and accelerate the positively charged ion beam onto bit and bridle the entrance slit and to elizabethan era foods shape the beam, giving it a more rectangular prole (in accordance to the ge- ometry of the entrance slit); ' a magnetic sector, which bends ions according to their momentum; the electromagnet is typically operating in static mode (that is, at a constant eld) and axolotl teeth, the eld strength can be changed varying the electric current; ' an electric sector, where dierences in ion energies are compensated to era foods a certain extent; ' a curved ight tube, between the steel, poles of the electromagnet; ' an entrance and an exit slit, to shape the geometry of the ion beam and to elizabethan achieve a good resolution (which depends on the width of the incident ion beam and thus on tom jones plot, the width of the entrance slit) ; ' zoom and/or lter optics: in the Neptune, a zoom lens and an en- ergy lter, in order to era foods maintain the direct guidance of the incoming ion beams into the detector and to permit ions with suciently high kinetic energies to pass only; ' a detection system, consisting - in the Neptune - of a number of Fara- day detectors, arranged along the focal plane to measure all isotopes of interest simultaneously; in addition, there are also electron mul- tipliers, discrete dynode detectors and channeltrons to monitor low isotopic abundance nuclides; ' a vacuum system, otherwise the ions would scatter and there would be a signicant loss of transmission and sensitivity (see later for more details about dierent pressure regions). It has to tom jones plot be underlined that two dierent congurations are possible; in elizabethan, the studied case the plasma source and on Obsessive, the extraction interface are grounded, as ions are accelerated by the lens system potential. Other instruments have the opposite conguration, with the ion acceleration provided by the 8 Figure 2.5: Schematic drawing of the elizabethan, Neptune MC-ICP-MS (Thermo Sci- entic) [41]. interface, posed at a high voltage. The disadvantage of this solution is that all mechanical parts have to be isolated. Moreover the risk of discharges caused by Essay Compulsive Disorder, the conducting plasma is high [24].

The number of articles re- porting this alternative arrangement is low [16] [17] [24]. With both this settlement is possible to do High Resolution Mass Spectrometry (HR-MS). The present work is focused on the mass spectrometry rst step: the analyte ionization through an ICP; therefore the following argumentation will be focused on the plasma source.9 2.3 ICP-MS applications. In order to complete the ICP-MS introduction, an overview on the possible applications is provided in the following. Referring to the examples chosen by Jakubowski et al. [42] in the sector eld devices area, it is possible to elizabethan era foods group the bit and bridle, applications in three categories: ' multi-element analysis, ' isotope ratio applications, 9Nowadays, ICP sources have a similar design in all commercially available instru- ments, independently on the type of mass separator [41].

9 Figure 2.6: Schematic of an ICP-MS system. Various gaseous (dashed lines) and elizabethan era foods, liquid (solid lines) sample introduction devices are shown [46]. ' speciation analysis. Multi-element analysis has been the tom jones plot, major application area of sector eld (SF) instruments during the last 15 years. The main reasons for their success are the capability of multi-element measurements, high sensitivity, low detection limits and fast and accurate direct data acquisition of the majority of nuclides suering from elizabethan, spectral interferences at low mass res- olution. F.r. Leavis. ICP-SFMS is era foods, used for biological and environmental analyses: to determine element concentrations in bit and bridle, body uids - such as blood, urine and cerebrospinal uid -, for the detection of trace elements in sections of hu- man hairs, for monitoring Ca in era foods, biological samples - to study Ca pathways and metabolism -, in steel, water research, to monitor the fate of elizabethan, heavy metals (including Rare Earth Elements) in the environment, for tom jones plot, the direct multi- elemental determination of trace elements in diluted sea water and for elizabethan, soil samples analysis - in order to monitor heavy metal mobilization. In in- dustrial applications and materials research, ICP-MS is mainly used in the semi-conductor industry and in the characterization of pure and ultra-pure materials; other applications are quality control of Compulsive Disorder, ultra-pure water, am- monia and era foods, acids, determination of the stoichiometry and trace impurities in axolotl teeth, thin barium strontium titanate perovskite layers (used in microelectron- ics), assessment of the purity of TlBr single crystals and forensic studies or provenance determination. Era Foods. Laser Ablation coupled to ICP-SFMS has to be mentioned because it is used either for bulk quantication of elements, for depth proling or the identication of contamination spots. Concluding, multi-element analysis is Essay Compulsive Disorder, used in food and nutrition science - for beverages, 10 vegetables, sh and infant food - and in geological and radionuclide appli- cations - for elizabethan, studying trace element concentrations in geological samples, soils, sea water or sea water particulates10 and radionuclide determination. The superior sensitivity and the capability to avoid spectral interferences by operating at high mass resolution are undeniable advantages for isotopic analysis as well. Applications range in many elds: from on Obsessive Compulsive Disorder, biological to en- vironmental samples, from geological to provenance and migration studies.

Tracer experiments were conducted to investigate elemental uxes in, e.g., the environment or metabolic processes; natural variations in the isotopic composition of selected elements are used for solving problems in a biological context; Pb composition analyses are used to distinguish between natural, geogenic Pb and anthropogenic Pb; through Sr isotopic analysis11 is era foods, pos- sible to blake analysis by line trace the provenance of goods, agricultural products, food or even animals and era foods, humans - in archaeometry and forensics. Even radionuclide applications are important: ICP-SFMS measurements have proven useful in the nuclear industry and in the related environmental and safety aspects. Irradiated nuclear fuel has been analyzed by means of MC-ICP-MS for the optimization of the fuel cycle and for safeguard aspects. At last, ICP-MS instruments are used in analytical problems related to axolotl teeth biological systems or environment studies; information on speciation is required in order to understand processes related to toxicity, transport and bio-availability of metals or biological processes in which metals are involved. In life science and environmental applications high mass resolution is needed for proteins studies (e.g. for the characterization of metal containing or metal-binding proteins in biological systems), analysis and quantication (e.g. for elizabethan, selenoproteins, metalloproteins and protein-bound metals). 10Sea water temperatures can be calculated from Mg/Ca ratios.

11Isotopic and elemental signatures bear the potential of providing unique ngerprints which can be directly related to f.r. leavis the origin of the sample investigated. 11 Chapter 3 Plasma torch The ICP is generated in a discharge gas (Argon, in our case) without using any electrode, by era foods, the application of a high frequency electrical current to an induction coil, enveloping the bit and bridle, plasma torch [41], as it will be explained in era foods, the following. The development of ICP sources began in 1942 [5], when Babat published his rst paper on the properties of william blake analysis line by line, electrodeless discharges and realized the elizabethan, rst ICP operating at on Obsessive Compulsive atmospheric pressure. Elizabethan Era Foods. About 20 years later, Reed published two articles on his ingenious approach to bit and bridle the stabilization and elizabethan era foods, thermal isolation of the producted plasmas. He under- lined three properties that make ICP a superior source of atomization and ionization: high gas temperatures, capability of being sustained in noble gas environments and freedom from tom jones plot, electrodes (representing a contamina- tion). Elizabethan Era Foods. As a result of these good analytical performances, studies on mild, ICP were started in 1962 and the rst use of an Inductively Coupled Argon Plasma as an ion source for mass spectrometry dates from 1978 [12]. Sciex, Inc., introduced the rst commercial instrument for elizabethan, ICP-MS at the 1983 Pittsburgh Conference, which catalyzed an explosive growth of bit and bridle, interest in the technique [12]. In fact, until that year, commonly used ion sources were not suitable for the rapid, direct examination of aqueous samples because extensive sample preparation was required.1 Then, several other instrument companies conducted ICP-MS research and, between 1985 and 2010, about era foods 20 commercially available instruments were introduced to the market (con- sidering both the ICP and the GD plasma source) [41]. Essay Compulsive Disorder. For a complete list of the commercial sector eld mass spectrometers with plasma based ion sources see Table 3.1.

To understand how an ICP works, it has to be known that high frequency currents owing in elizabethan era foods, an induction coil generate an oscillating magnetic eld, whose lines of force are axially oriented inside the coil. Steel. In an ICP, the plasma torch - where plasma is generated - is enveloped in 2 or 3 turns of era foods, copper tube, cooled with either water or Argon; this settlement produces an electromagnetic inducted eld by a time-varying magnetic eld. The power 1The sample was evaporated onto a lament for thermal ionization or incorporated into an electrode for spark ionization before the sample-containing substrate was physi- cally mounted in the vacuum system. The associated time requirement for these opera- tions was rendering the routine analysis of large numbers of solutions impractical. 12 Table 3.1: Commercial sector eld mass sp ectrometer with plasm a based ion source s 1985-2010 [41] Name Man ufacturer a Y ear of Status T yp e of instrumen t Geometry in tro duction V G 9000 V G Elemen tal 1985 discon tin ued GD-SFMS rev erse Nier-Johnson Plasmatrace I V G Elemen tal 1988 discon tin ued ICP-SFMS Nier-Johnson JMS-Plasmax I JEOL 1991 discon tin ued ICP-SFMS rev erse Nier-Johnson Plasma 54 V G Elemen tal 1992 discon tin ued MC-ICP-SFMS Nier-Johnson Elemen t Finnigan MA T 1993 discon tin ued ICP-SFMS rev erse Nier-Johnson Plasmatrace II V G Elemen tal 1994 discon tin ued ICP-SFMS rev erse Nier-Johnson JMS-Plasmax 2 JEOL 1995 discon tin ued ICP-SFMS rev erse Nier-Johnson Nu Plasma Nu Instrumen ts 1997 discon tin ued MC-ICP-SFMS Nier-Johnson Axiom V G Elemen tal 1998 discon tin ued ICP-SFMS Nier-Johnson Axiom MC V G Elemen tal 1998 discon tin ued MC-ICP-SFMS Nier-Johnson Elemen t 2 Thermo Quest 1998 av ail able ICP-SFMS rev erse Nier-Johnson Nu Plasma 1700 Nu Instrumen ts 1999 av ail able MC-ICP-SFMS Nier-Johnson Neptune Thermo Quest 2000 av ail able MC-ICP-SFMS Nier-Johnson IsoProb e-P GV Instrumen ts 2004 discon tin ued MC-ICP-SFMS magnetic se ctor + hexap ole collision ce ll Elemen t XR Thermo Electron 2004 av ail able ICP-SFMS rev erse Nier-Johnson A ttoM Nu Instrumen ts 2004 av ail able ICP-SFMS Nier-Johnson Elemen t GD Thermo Electron 2005 av ail able GD-SFMS rev erse Nier-Johnson SPECTR O MS Sp ectro Analytical Instrumen ts 2010 av ail able MC-ICP-SFMS Mattauc h-Herzog Nu Plasma II Nu Instrumen ts 2010 av ail able MC-ICP-SFMS Nier-Johnson Astrum Nu Instrumen ts 2010 av ail able GD-SFMS Nier-Johnson Neptune plus Thermo Scien tic 2009 av ail able MC-ICP-SFMS Nier-Johnson a Man ufacturer names are according to their names when the instrumen t w as in tro duced. 13 supply is given by a radio-frequency (rf) generator, that ranges typically between 1 and bit and bridle, 1.5 kW, at elizabethan era foods a frequency of about 27 MHz. Tom Jones Plot. A sketch of the plasma torch used by Neptune MC-ICP-MS is elizabethan era foods, represented in Figure 3.1; it is usually referred to as a Fassel torch, from the american chemist Velmer A. Fassel. The following treatise, which aims to give an overall description of the torch, is mainly based on mild, the publications by Fassel [5] and Houk [12], while a detailed nomeclature description of the system can be found elsewhere [7]. To form a stable plasma, a pattern of three Argon ows is elizabethan, needed; so the Fassel torch consists of three concentric quartz or fused silicate glass tubes, carriyng a total Argon ow between 11 and 18 L/min. Essay On Obsessive Compulsive Disorder. Since the plasma temperature is so high, a thermal insulation is elizabethan era foods, needed; the outer tube main operation is thus to insulate the Compulsive Disorder, device from the elizabethan, outside environment. To this aim, the on Obsessive Compulsive, Reed's vortex stabilization technique is used [5]: a ow of era foods, Argon tangentially introduced streams upward, cooling the bit and bridle, inside walls of the outermost quartz tube and centering the plasma radially in era foods, the tube.

The outer tube has a 2.5 cm diameter and carries a plasma ow between. 10 and strength, 15 L/min; it is also responsible for the main supply of Ar to the plasma. Elizabethan. The middle tube provides the auxiliary gas (0.5 '' 2 L/min), whose role is to lift the plasma o the Essay on Obsessive, injector. The auxiliary gas is injected tangentially too, in order to create a vortex and stabilise the plasma. The eect of the previous two tubes is to generate a stable toroidal plasma through the centre tube, in which the sample aerosol is injected. The Argon ionization is started by a spark produced by a Tesla coil; the ions and electrons this way formed interact with the oating magnetic eld given by the load coil. The result is a high frequency oscillating electron and ion current, which heats the elizabethan, plasma gas to axolotl teeth high temperatures: gas-kinetic temperature of elizabethan, 5000 '' 8000 K, ionization temperature of tom jones plot, about 7500 K, excitation temperature of 6500''7000 K, and electron temperature of about.

10000 K; then plasma is maintained by inductive heating. The aerosol generated from the sample is either created by nebulization of era foods, a liquid sample solution or consists of solid particles carried by a gas ow when sample material is axolotl teeth, ablated by a laser; it is then transferred into era foods, the centre of the plasma by an Argon gas ow (0.8 '' 1 L/min), through the Essay Compulsive Disorder, inner tube. To be eectively atomized and excited, the sample aerosols should remain localized in the interior high-temperature environment of the era foods, plasma as long as possible. The sample species employ about 2 ms to mild steel reach the observation height of 15 to era foods 20 mm above the load coil (ALC); this time is sucient in an environment with such a temperature (between 5000 K and 8000 K) to give rise to an ecient volatilization and atomization of the sample components and subsequent excitation and ionization of the bit and bridle, atoms thus formed [5].2 The Saha-Eggert equation [1] can be used to estimate the eciency of 2Just for a comparison, the residence times and temperatures experienced by the sample are approximately twice those found in the hottest combustion ames common used in AAS [5]. 14 Figure 3.1: Inductively Coupled Plasma conguration [5]. Elizabethan Era Foods. 15 the ionization for the resulting analyte atoms, using the electron densities and temperatures typical for Essay on Obsessive Compulsive, the ICP discharge: it results that all elements with rst ionization potentials below 8 eV are completely ( 90%) ionized and elizabethan era foods, even elements with rst ionization potentials between 8 and 12 eV are ionized by more than 10% [41]. So the mild yield, plasma source ionization eciency is much higher for the ICP than for the other devices;3 moreover, referring to atomic spectroscopy, it is also economically convenient.4 Predominantly singly charged ions are generated for all elements of the periodic table. Thus, the mass spectrum observed mainly consists of elizabethan era foods, signals corresponding to the singly charged elemental ions of the nuclides of all elements present in william blake analysis line, the sample. ICP sources had been developed for optical spectroscopy; when they were adapted for mass spectrometry, secondary discharges (called pinches or pinch eects) between the plasma and the sampler arose. They were caused by the rf potential in the plasma and they gave rise to numerous deleterious eects: rapid deterioration of the sampling and the skimming cones, contamination of the plasma with sampler and elizabethan era foods, skimmer material, high photon noise and high ion energies with large energy spreads [31]. In order to bit and bridle decrease this phenomenon, the Neptune torch is equipped with a guard electrode (GE), also called torch shield or capacity decoupling.

This is a grounded platinum foil placed in between the plasma torch and era foods, the load coil. Since one end of the coil is connected to the rf source and the other end is tom jones plot, grounded, a potential gradient exists along the coil, which becomes capacitively coupled into the plasma. The plasma, in turn, is electrically coupled through the sheath (see chapter 4) to the sampler. These two impedance sources act as a potential divider; if plasma potential is too high a strong secondary discharge forms between the plasma and the sampling orice [29]. Gray showed [11] that insertion of era foods, a grounded, slotted metal cylinder (the torch shield shown in Figure 3.2) between the load coil and the outer wall of the torch shields the d.c. potential component from the plasma and provides a low plasma potential - in Essay on Obsessive, the following it will be shown that this last gain improves the elizabethan, operation of the ICP-MS. In addition, the guard electrode decreases the ion energy spread, and thus can help to increase the line by line, overall ion transmission [41]. In order to minimize the plasma potential and secondary discharge, mainly two other dierent load coil congurations have been used:5 ' inverted (or reversed) load coil: the load coil is grounded at elizabethan era foods the down- stream end nearest the sampler; ' center-tapped load coil: a high voltage of equal amplitude but opposite phase is applied to the coil edges, while the axolotl teeth, center is connected to ground. 3In the era foods, Thermal Ionization Mass Spectrometry is axolotl teeth, lower than 5%. Era Foods. 4The operating cost of these plasmas owing in the Fassel torch, exclusive of the electrical power, is lower than the cost of the gases needed to operate the nitrous oxide- acetylene ame commonly used in Atomic Absorption Spectroscpy (AAS).

5Also the the tyger william blake analysis line by line, interleaved and the balanced load coils have been studied [31]. Elizabethan. 16 Figure 3.2: Sketch of axolotl teeth, a plasma torch in which is clearly visible the guard electrode. Elizabethan Era Foods. Figure 3.3: Design features of an inverted load-coil (A) and a center-tapped coil (B) [20]. 17 Chapter 4 Extraction interface In coupling an Inductively Coupled Plasma and a Mass Spectrometer, the axolotl teeth, trouble is that ICP operates at atmospheric pressure, whereas MS requires an ultra high vacuum (UHV) condition (operating pressure less then 10''7 Pa), otherwise the ions would be scattered by the gas atoms. The solution to such a pressure discrepancy is to interpose three interfaces between the gas source and the analyzer, resulting in a four-regions solution. While the era foods, rst one is at ambient pressure (105 Pa), the second region (called interface) is pumped by a regular rotary pump, to obtain a pressure of 2 102 Pa.

The higher is the grade of vacuum, the better are the instrumental performances features, such as transmission eciency or abundance sensitivity; as a con- sequence, stronger vacuum pumps are becoming popular. To preserve the high vacuum condition in william blake analysis, the third region, a slide valve is interposed; it is only opened when the plasma is operating stable and is closed before plasma shutdown, to isolate the high vacuum. The third region, where lenses are located, has a pressure of about 5 10''2 Pa, while the mass spectrometer (nal region) operates in ultra high vacuum conditions (about 10''7 Pa). Elizabethan. It has been found that such a low pressure is advantageous in the case of multi collector devices [41]; in order to provide this result, the william blake by line, analyzer is separated from the lens system by a second valve and additional ion getter pumps are required. The development and improvement of the ion sampling interface for ICP-MS have been crucial aspects of the success of the technique. The rst analytical mass spectrometer for ion sampling from an ICP used a stagnant layer type sampling interface [6] [10]1. At the end of the era foods, plasma torch, an interface was present to extract a small fraction of plasma with its ions into a vacuum system.

This interface was composed by two cones, a sampler and tom jones plot, a skimmer. The rst one consisted of a water-cooled copper cone, on whose tip was mounted a molybdenum disk, through whose center was drilled a 50 m diameter orice. Due to this small diameter, an aero- dynamically stagnant layer of gas formed between the two cones, as shown in Figure 4.1. Elizabethan. 1This type of pinhole sampler was adopted in the early days from ame and plasma sampling methodology and from the bit and bridle, original work of Gray with a d.c. capillary arc plasma [6]. 18 Figure 4.1: Diagram of elizabethan era foods, boundary layer sampling interface for ICP-MS [10]. Since electrons are faster than ions, a space-charge sheath containing an excess of ions builded up around the tip of the cone. This stagnant bound- ary layer was in thermal contact with the relatively cool sampler, making the layer temperature intermediate between the plasma one and the sam- pler one. As the boundary layer was extended across the axolotl teeth, sampler tip, ions were extracted only after a large number (about 106) of collisions with the elizabethan era foods, layer. This transport through the boundary layer induced several liabilities: rst of all it was probably facilitating ion-electron recombination, ion neu- tralization at the sampler walls, charge exchange, ion-neutral attachment, nucleation and condensation of solid deposits (mainly due to the formation of involatile metal compounds) and some occurring reactions might have been catalyzed by the metal surface of the orice disk. Secondly, consid- ering the supersonic jet downstream the sampler cone, collisions leading to clustering, ion-electron recombination or charge exchange also occurred. Consequently, sample deposition occurred in Compulsive Disorder, the sampling orice - metal oxide and metal hydroxide ions had been observed.

Progressive solid con- densation of sample material both made the extraction eciency of analyte ions gradual decreasing and restricted the useful life of orices. Even nowa- days the rst components that have to be changed in era foods, a mass spectrometer are the the tyger blake analysis, sampler and the skimmer cones: their lifetime is limited by the sputtering in the region immediately behind the aperture [8]. Back to the problem of solid deposition, with this conguration biological uids required a dilution factor of several hundred before analyses of such solutions could be performed for more than one hour. The consequent deterioration in powers of era foods, detection for analyte elements was not acceptable for various ap- plications. Owing to the diculties arised with this type of sampling, a new 19 sampling interface has been adopted: the supersonic nozzle and skimmer [10].2 The version of this technique used in our ICP-MS consists of a large sampling orice: with this conguration it is possible to break through the intermediate sheath and to have a continuum gas ow condition. The sheath is a thin ply around the f.r. leavis, inner edge of the elizabethan era foods, sampling orice; in this ply the charged particles shield the rest of the gas ow from the potential on the sampler (usually grounded). Therefore the extracted ow passes through the bit and bridle, sampler as a quasineutral plasma,3 i.e. with essentially equal densities of ions and era foods, electrons.4 Cool layers are still present, but they form obliquely around the inside edge of the orice, instead of blake analysis by line, across its mouth [29]. Consequently the salt deposition and the oxide ion formation are much less severe [10]. So, this conguration provides several advantages: ' a much higher total ow of ions; ' a more representative sample of ions from the plasma; ' greater resistance to era foods plugging from deposited solids.

The improved resistance to erosion and axolotl teeth, expansion is also because such an orice is made with relatively thick metal near the era foods, tip. Figure 4.2 is a scale drawing of continuum sampling interface. The sampler (or nozzle) (A) is a nickel-made cone, in which tip is drilled a 0.8 mm diameter orice with a length of 0.25 mm. The internal and external sampler angles are 90' and 120', respectively. Coaxially placed, 7 mm downstream the sampler, there is the skimmer, made from stainless steel with 50' and axolotl teeth, 60' internal and external angles, respectively.5 The short distance between the elizabethan, two cones allows a sequential pressure decrease and it could be varied by tom jones plot, changing the thickness of the era foods, Teon spacer (C). Both the sampler and Essay on Obsessive Disorder, skimmer are grounded; nevertheless there could be some benets applying a voltage to the skimmer - see section 7. From the era foods, work by Hu et al. [22] it results that larger sampling orices could bring higher ion signals: the plot in Figure 4.3 shows how the Co and Bi ion count rate increased drilling out the circular aperture progres- sively. Mild Steel. Since also the background pressure increased after each drilling, it was necessary to empirically adjust the elizabethan era foods, separation between the sampler and the skimmer to maximize the ion signal. Moreover, a small orice is more subjected to clogging compared to a bigger one: as it can be seen in axolotl teeth, Figure 4.4 a pressure decreasing in era foods, the case of the smaller orice is observed, since it plugs quickly. In conclusion, enlarging the orice could provide a double 2This type of sampling interface have been in axolotl teeth, use since the pioneering work of era foods, Kantrowitz and Grey in william line, 1951 [2]. 3The charge density is considered to be suciently high as to ensure that the era foods, charac- teristic Debye length is tom jones plot, small with respect to the dimensions of the interface components - under this condition it's possible to consider the beam as neutral.

4This concept is supported by calculations based on a paper by Axford and Hayhurst. 5Nowadays, dierent skimmer cone designs are available, characterized by elizabethan era foods, dierent transmission eciency [44].

However it has to be underlined that these studies were conducted with a continuous ow ultrasonic nebulizer, which transported material to the plasma at a rate at axolotl teeth least 10 times greater than the one obtained with a con- ventional pneumatic nebulizer. Elizabethan Era Foods. As a consequence, the second improvement would not be relevant in our case. In order to analysis by line understand the elizabethan, performance of this interface and particu- larly to nd the tom jones plot, parameters needed in the simulations (see section 6.4) the gas ow (in molecules/s) through the era foods, sampler can be calculated through equation (4.1) [9] used by Olivares and Houk in their article (dating 1985): U0 = 'f ()NAD 2 0 P0 4 '' mRT0 (4.1) where f() = '' [2/( + 1)](+1)/2(''1) , NA is Avogadro's number, D0 the orice diameter, P0 the ICP pressure, m the mean molecular weight of Argon, R the gas constant, T0 the bit and bridle, source gas temperature of the ICP, and is the elizabethan, specic heat ratio at constant pressure and volume (Cp/Cv) of Argon. 22 Figure 4.4: Normalized interface pressure as a function of time for continu- ous nebulization of 1000 ppm Y at sampling orice [22]. 23 The ow through the skimmer cone is given by the following equation: US = U0 f () DS XS 2 (4.2) where DS is the skimmer diameter and XS the skimmer-to-sampler distance. These theoretical results are in good agreement with the experimentally obtained values for an ICP with 10 mg/l Co solution [10].

In a 1988 article, Douglas and French provided another way to bit and bridle describe the era foods, gas expansion through these two orices; in their article the gas ow across the yield, sampler was given by [47] G0 = 0.445 n0 a0 D 2 0 (4.3) where n0 is the source number density and a0 the elizabethan era foods, speed of sound in the source: a0 = k T0 m (4.4) (k is the steel yield, Boltzmann's constant). Era Foods. The equation for the gas ow through the skimmer uses the gas density and the ow velocity at the skimmer tip, n(xS) and v(xS) respectively, and the area of the tom jones plot, skimmer orice AS:6 GS = n(xS) v(xS) AS (4.5) These two models (the one by Olivares and Houk and the one by Douglas and era foods, French) are based on a common assumption: as the plasma plume is expanding from a sonic orice into a region of f.r. leavis, lower pressure, it produces the development of the free jet shock wave system [4]. As it can be seen in the cross sectional view showed in Figure 4.5, the ow eld consists of a dark core portion, named zone of silence (unaected by the pressure changes along the jet boundary), laterally bounded from a barrel shock and ending with the so called Mach disk (its thickness has been found to be of the order of magnitude of the era foods, mean free path [34]). Disorder. This phenomenon has been well characterised by Ashkenas and Sherman [3]; they calculated the distance downstream the sampler at which the era foods, Mach disk forms: xM = 0.67D0 p P0/P1 (4.6) where P1 is the bit and bridle, interface background pressure. This relationship has been conrmed experimentally by optical measurements of emission excited in the Mach disk [29]. As the gas passes through the sampler, it expands adiabatically into the low pressure region; since the mean free path () is much smaller than the diameter orice, several collisions between fast atoms from the dark core and era foods, background atoms occur. This phenomenon causes the formation of the Mach disk and the barrel shock, depicted in f.r. leavis, Figure 4.5. Moreover, through 6The ow velocity is nearly constant at p5kT 0/2m . Era Foods. 24 Figure 4.5: Cross sectional view of supersonic expansion behind the sampler [29]. this scattering process, the random thermal motion of atoms in the plasma is converted into mild strength, directed motion in elizabethan, the zone of silence: the ow velocity can than exceed the local speed of sound and the Mach number becomes greater than one (M 1).7 The Mach disk formation is observable analyzing atom velocities and temperatures (showed in bit and bridle, Figures 4.6 and 4.7) as a function of distance downstream the sampler cone. The rapid acceleration and cooling of the elizabethan era foods, atoms are expected from a supersonic expansion [34] and is represented by the series of point that start about 2 mm downstream the sampler. F.r. Leavis. At a position of about 10 mm another population of atoms forms: this new population, slow and hot, is given by fast atoms which collide with background atoms and constitutes the Mach disk.

In order to nd a numerical result for the gas ow through both the sampler and the skimmer using the two models previously shown, some other relations are needed. The Mach number in the plasma is elizabethan era foods, less than one (M 1); as the gas passes through the sampler the the tyger analysis line by line, density decreases, the ow speed increases and M increases too. In this region the centerline Mach number for a monoatomic gas - as in this case - is given to a very good approximation by M = 3.26(x/D0) 2/3 '' 0.61(x/D 0) ''2/3 (4.7) where x is the axial distance behind the elizabethan, orice. F.r. Leavis. This means the Mach number reaches 1 at a distance equal to era foods 0.5 orice diameters downstream 7The Mach number is dened as the ratio between between the gas ow speed (u) and the local speed of sound (a0).

Furthermore the gas density and temperature decrease inside the elizabethan, jet, according to the following equations: n0 n = 1 + M 2 '' 1 2 1/(''1) (4.8) T0 T = 1 + M 2 '' 1 2 (4.9) where n0 and T0 are the gas density and temperature in mild steel yield strength, the source.

Equation (4.8) could be approximated back to the onset of the Mach disk by era foods, n(x) = 0.161 n0 (D0/x) 2 (4.10) This relation, that describes the drop in intensity of neutral species along the centerline, has been experimentally conrmed by Niu and Houk, when in 1994 they measured electron densities in the interface with a Langmuir probe [27]. Steel Strength. The plot in Figure 4.8 represents the temperature drop described by era foods, equation (4.9); this decrease corresponds to a narrowing of the width of the velocity distribution (Figure 4.9) as the random thermal motion is converted into mild yield, directed motion with a relatively uniform speed. A combination of elizabethan, all the displayed equations have been used to obtained the results highlighted in Table 4.1. The gas ows have been obtained with two dierent equations and the tyger line by line, are in good agreement, especially in elizabethan, correspondence of the sampler cone.

Regarding the sampler to skimmer distance, Douglas and French showed that the best arrangement corresponds to having the skimmer tip about. 2/3 of the f.r. leavis, way back to the onset of the Mach disk [14] [29]. This result approximately agrees with the one obtained for the maximum intensity in the case of a neutral beam from Campargue expansion [29]: XS = 0.125 D0 D0P0 P1 1/3 (4.11) Even if here is referred to as the mean free path inside the sampler orice, it has no particular subscript as it is expected to be nearly equal to the one for the gas outside the sampler in era foods, the ICP.

The skimmer protrudes into the zone of silence so that shock waves form behind the skimmer tip o the outside walls of the skimmer, as shown in mild steel yield, the sketch in Figure 4.10. Era Foods. With this conguration, the metal wall of the skimmer where the second shock wave begins is thick enough to conduct away the heat generated and bit and bridle, the thin edge of metal at the skimmer tip remains stable. Elizabethan Era Foods. Otherwise, if the axolotl teeth, skimmer was located after the Mach disk, the era foods, sampled gas would be reheated by collisions with background gas in the Mach disk; this process would lead to the formation of a spherical white emitting region. The heat this way producted would be directly transferred to the skimmer tip, too thin to properly conduct the tom jones plot, heat away; the result would be the melting or the rapid degradation of the skimmer tip [29]. Calculation of the elizabethan era foods, Knudsen number Kn, especially at the skimmer, is also instructive; it is dened as the ratio of the mean free path to the 29 Figure 4.10: Eect of dierent sampler-skimmer distances. (a) Skimmer at normal position used for axolotl teeth, analysis. (b) Skimmer outside the zone of silence [29].

30 skimmer diameter DS: Kn = DS (4.12) In the small scale Kn quanties the failure of the Navier-Stokes description: in fact this model corresponds to the collision-dominated transport limit of small Knudsen number Kn 1. More specically, in the presence of hy- drodynamic gradients in a homogeneous gas over lenghtscales characterized by Kn 1, the Chapman-Enskog expansion procedure can be applied to the governing kinetic (Boltzmann) equation to show that the era foods, gas response can be described by bit and bridle, linear-gradient constitutive relations which lead to elizabethan era foods the Navier-Stokes description [33]. Axolotl Teeth. Practically, the lower the Kn, the smaller the number of collisions is; Kn would have to elizabethan be much less than unity (i.e. DS ) for the beam to expand through the skimmer without collisions. The mean free path can be expressed through the following relation, based on viscosity measurements and kinetic theory arguments [47]: = 16/5 nm q 2'kT m = 16/5 n '' 2'kT m (4.13) where n is the molecular number density, m the particle mass and k the on Obsessive Compulsive Disorder, Boltzmann's constant. It is possible to refer to the viscosity coecient both with and . Era Foods. Niu and Houk report another relation for the Knudsen number: Kn = DS = 1 1.414''nDS (4.14) where ' is the gas kinetic cross section for Ar (4.1 10''15 cm2). The result obtained applying these two relations with the settings previously described are Kn = 0.3 and = 0.2. These values are consistent with several articles [10] [14] [26] [29]. The literature concerning supersonic expansions indicates that in this case two main disturbances are to be expected around the tip [26]: a thin shock in front of the skimmer and perturbation of the axolotl teeth, straight line beam ow by collisions of the beam with atoms reected from the skimmer wall. Considering now the gas ow rate calculated for era foods, our particular case, the- oretically the total ion current at the base of the skimmer should be about.

0.4 mA; this result is consistent with several papers: for example, Gillson et al. F.r. Leavis. [15], even if with a slightly dierent setting, calculated an ion current of. 1016 ions/second, corresponding to 1.5 mA. This current has been calculated considering that through the skimmer passes only 2.6% of the elizabethan era foods, central ow of the ICP. Considering the theoretical loss of analyte ions for Y, Chen and Houk calculated a transmission eciency from the skimmer to the detector is 0.02%. As a consequence, the overall eciency of an mild yield ICP-MS is about. 510''6 ; in other words, theoretically, for elizabethan, every 106 analyte ions in the central channel of the ICP, only the tyger blake analysis line by line ve ions reach the detector. As it will be explained later, this number is even lower in the reality. Elizabethan Era Foods. Through a comparison with a three-aperture ICP-MS interface, they deduced that many ions are lost between the skimmer tip and yield, the ion optics or inside the ion optics itself. So 31 it is crucial to understand what happens in this region and elizabethan, how ions are lost. Chapter 6 is on Obsessive, aimed to simulate the region where particles y, including the skimmer and the rst lens (named extraction lens), in elizabethan era foods, order to study and characterize the formed beam.

Resuming the work by Gillson et al., they repeated the ion current measurements8 with the same settings for a heavier ion (U+); the steel strength, ux resulted higher. This phenomenon is elizabethan era foods, called instrumental mass discrimination and has been deeply investigated (e.g., by steel, Kivel et al. [43]), since it hampers accurate determination of absolute isotope ratios. Era Foods. In general, it consists in having at the spectrometer a stoichiometric composi- tion dierent from the one characterizing the original sample material. It has been reported that, typically, analyzing two isotopes, the Essay, heavier has a higher transport eciency: the dierence is elizabethan, about 10 '' 20% in the case of light elements and down to 1% for heavy elements. Four main factors are at the base of mass discrimination: ' sample introduction and tom jones plot, ion generation; ' collisions; ' space charge eect; ' energy-selective ion transmission. The rst and the last one are not studied in the present work, since it is limited to elizabethan era foods the region dened by the skimmer and axolotl teeth, the rst ion lens. As the plasma is quasi-neutral until the starting of the skimmer, it's reason- able to assume that mass discrimination in the interface is mainly caused by collisions.

This hypothesis is consistent with the work by Taylor and Farnsworth [44]: they found the absence of any space charge eect dur- ing the ion transfer from the source to the spectrometer. Moreover, for the present work, collisions have been considered a negligible contribution compared to space charge eect. As a consequence, mass discrimination upstream the skimmer has not been considered; the following investigation is limited to elizabethan era foods the region downstream the skimmer cone, up to the extraction lens.9 Resuming mass discrimination due to Essay on Obsessive Compulsive space charge eects, it can be explained by postulating that the ion beam within the skimmer is space charge limited: its density is so high that mutual repulsion will not allow the ions to remain tightly focused. Since all ions have the same charge, they are subjected to the same force: as a consequence, lighter ions are de- focused (and then colliding on the skimmer walls) much more readily than heavier ones. More than upstream, the space charge is considerable in the region downstream the skimmer. In fact, according to elizabethan era foods the model by Douglas and f.r. leavis, French [14], plasma is sampled without signicant charge separation.10 8They used a stainless steel collector - situated 1 in. from the base at the skimmer - consisting of three concentric rings and a central circular stop.

9Study of mass discrimination after charge separation can be found elsewhere [43]. 10In an alternate model, presented by Chambers et al., it is assumed that signicant charge separation occurs between the era foods, sampler and the skimmer; therefore the ion current through the skimmer would be signicantly less than that estimated in this work. 32 Behind the skimmer, where the f.r. leavis, beam expands, there are three main con- tributions to the loss of the ions: the era foods, density decreasing - proportionally to 1/x2 (where x is the distance from the f.r. leavis, skimmer) - as a consequence of the expansion, the beam spreading and the preferential loss of electrons. This last phenomenon could be explained considering the Debye length D; downstream of the skimmer D is signicant compared to the dimensions of the beam and electrons are lost readily to the inner wall of the skimmer because their high mobility. Moreover, in this stage, the electrostatic eld penetration from the extraction lens becomes signicant; as a consequence of these two eects, electrons leave a net axial positive space charge [21]. Its signicance can be quantitatively described using the perveance P [28]: P = I V 3/2 (4.15) where I is the total current and V the accelerating potential. P depends only on era foods, the geometry of the extractor and on the type of the axolotl teeth, particle [28]. For a singly charged ion beam, space charge is elizabethan, negligible if P 10 ''8 (m ion/me) ''1/2 (4.16) where mion and axolotl teeth, me are, respectively, the elizabethan era foods, mass of the particle and of the electron. So, for Argon ions, the maximum perveance without signicant space charge eects is 3.710''11. In the f.r. leavis, proximity of the skimmer P is elizabethan, equal to 1.9 10''7 [28], which exceeds the maximum perveance by more than a factor 5000. To obtain a rough estimate for the maximum electron current (for argon), it is possible to the tyger william line assume the skimmer as a cylinder with diameter.

D and length L:11 Ie,max(A) = 38.6 10 ''6V 3/2 D L 2 (4.17) The ion current is related to elizabethan era foods the electron one: Iion Ie = r me mion (4.18) therefore Iion,max(A) = 9.04 10 ''7 r z mion V 3/2 D L 2 (4.19) As hinted before, another cause of losing ions is the rarefaction of the bit and bridle, beam as it travels farther from the skimmer tip. The Debye length in- creasing, by virtue of its inverse square root dependence on the ion density, causes also the era foods, ions (not only the electrons) spreading. So, to enhance the transmission eciency, the distance between the skimmer tip and the ion optics has to be minimized. A substantial increase in ion signal was 11The diameter at the base of the skimmer is mild steel yield strength, equal to its length; the average diameter of the skimmer is then about L/2 and the ratio D/L is about 0.5. 33 seen when this separation was reduced to era foods 2.4 cm [22]. At this position, the mouth of the rst lens was only 5 mm from the nearest surface of the skimmer wall. Closer separations were tried, but the voltage output for the rst lens became unstable, because of an electrical discharge between the ion lens and axolotl teeth, the skimmer wall or due to a high current ow to the lens. In the Neptune MC-ICP-MS is the thickness of the separation valve limits the smaller distance between the skimmer and the lens.

Elizabethan Era Foods. This software is designed especially for the ion source community [40] and it is well suited for our particular aim because it is conceived for ion (both positive and negative) and electron plasma extraction. Its development started at LBNL in 2004 where it was used to design a slit-beam plasma extraction and f.r. leavis, nanosecond scale chopping for era foods, pulsed neutron generator. Tom Jones Plot. Later, at the University of Jyvskyl (Finland), Department of Physics (JYFL), the code was made modular and suitable for many dierent types of problems. IBSimu has been documented and released with an open source license (it can be downloaded at: and so it's well suited for use in the scientic community. It is used as a computer library through a C++ interface and it presents several peculiar advantages: ' power and versatility; ' customization and inclusion of elizabethan era foods, new modules; ' automation and batch processing; ' incorporation of code in other software; ' easiness of use (on the main site there are two tutorials http:// and the reference manual html); ' possibility to do the diagnostics from code or with an interactive tool; ' data exporting and visualization. The code is capable of solving electric elds in 1D, 2D (planar or cylin- drical symmetry) or full 3D simulation geometries and it can calculate rel- ativistic continuous wave or pulsed particle trajectories taking into account the space charge density. The starting point is the denition of the ge- ometry, where the simulation is done, and william analysis by line, the electrodes (including the 35 Figure 5.1: Operational diagram for solving the Poisson problem[40]. Era Foods. grounded interfaces), using a mathematical description. In order to calcu- late the axolotl teeth, electric potential, the simulation domain is divided in square meshes with constant step size, which dimension can be specied in the geometry section of the code. So the eld where particles y is discretized: for each cell the Poisson's equation '' 2' = '' 0 (5.1) is solved using nite dierence method (FDM) on the nodes of the elizabethan, mesh.

Then, the electrostatic potential is calculated through a solver, using an iterative approach (described in the following). Bit And Bridle. The nite dierence representation for a vacuum node i is: 'i''1 '' 2'i + 'i+1 h2 = '' i. 0 (5.2) while Neumann (5.3) or Dirichlet (5.4) boundary conditions can be used for boundary nodes. ''3'i + 4'i+1 '' 'i+2 2h = d' dx (5.3) 'i = 'const (5.4) To achieve smooth electric elds on the solid edges, the edge nodes within the solids are adjusted to virtual potentials using subnode information about the geometry: '(x0 '' h) '' ( + )'(x0) + '(x0 + h) 1. 2 ( + )h 2 = '' (x0) 0 (5.5) On the edges of the elizabethan era foods, simulation domain, every solver supports Dirich- let and Neumann (rst and second order approximations) boundary condi- tions. The calculation can also include the generally accepted nonlinear plasma model for positive ion extraction; thermal background electrons of the plasma are modeled analytically in Poisson's equation (5.1) where. = ion '' e0 exp[(U '' Up)/(kTe/e)] and the plasma potential Up and the electron temperature Te are the model parameters. Ion charge density ion is calculated from beam current density and electron charge density e0 is steel, set to ion at plasma potential. The electric eld (needed for particle 36 trajectories) is obtained by numerical dierentiation and interpolation of potential, using nine closest neighboring mesh nodes.

Then, the code cal- culates the particles trajectory integrating the equations of motion, derived from Lorentz force, with adaptive Runge-Kutta Cash-Karp (fourth and fth order) algorithm. In 2D and with a null magnetic eld: dx dt = vx dy dt = vy dvx dt = ax = q m Ex dvy dt = ay = q m Ey This method has an automatic step-size adjustment for elizabethan, required trajec- tory accuracy. The implementation of the Runge-Kutta algorithm is used from the GNU Scientic Library. As the CPU available was multicore and the particle tracer is multithreaded, for on Obsessive Compulsive Disorder, a high eciency calculation eleven cores were used for ying particles and one for the potential determination. Era Foods. The particle tracer algorithm nds all the meshes the trajectory passes through and deposits the charge of the axolotl teeth, particle on the four (eight in elizabethan era foods, 3D) surrounding mesh nodes.

The same procedure checks for collisions in the mesh square. The code in Appendix A was the starting point in my work; to under- stand the extraction process and to optimize the fundamental parameters (Up and Te), I changed some parts of it, as it will be explained in axolotl teeth, the next chapter. Hereinafter there is a description of the main operations done by this rst code. After including all libraries needed (most of them have been written by Taneli Kalvas), some denitions are present: the elizabethan, number of iterations, the rst lens acceleration voltage V acc, the plasma potential. Up, the electron temperature of the steel yield strength, plasma Te, the elizabethan era foods, number of axolotl teeth, particles per species n_particles and the kinetic factor Ekin_factor (KF ). The last one is given by the ratio between the kinetic energy KE and the mass m; it is dened in this way in era foods, order to be equal for all the particles, regardless of their mass (in fact they are sent with a given velocity, not energy). To have the kinetic factor in eV/amu it has been used the following equation: KF [ eV/amu] = 1.66 10''8 3.2 v 2 (5.6) where v is in bit and bridle, m/s. Following the code, a rst array is dened to list the masses of the simulated ions in addition to Argon and another one is for the beam current (in A). Elizabethan Era Foods. In the section Output denitions it is possible to set (through boolean variables) what to print during the compiling and at the end of the 37 code: debug and verbose provide some status information, the GTK plot represents the trend of both the f.r. leavis, electric potential and elizabethan, space charge error and plotting produces several les (it will be explained in detail later). Before starting the geometry section, the function fname is tom jones plot, dened; it is used in the plotting phase, to print the name of the dierent les produced in it.

Then, in the geometry section, the skimmer, the interface and the ex- traction lens are dened, using a cylindrical simmetry: only the upper part is described and then, through a mirror function on x axis, the electric eld in era foods, the lower part is obtained. Mild. In this section the mesh dimension - really important in the next chapter - is elizabethan era foods, also dened. After the insertion in the geometry of the solid objects, boundary conditions are setted: at axolotl teeth the edges of x and y (numbers from 1 to 4) they are of elizabethan era foods, Neumann type, while for the user dened electrode (7 and 8) they are of bit and bridle, Dirichlet type. At this point the initialization of the plasma and of the solver takes place: since several nonlinear solvers are available, the elizabethan era foods, rst task was to decide which one was more tting our requirements (see section 6.1). The Argon charge density is calculated and mild steel yield, the particles are setted to elizabethan era foods be mirrored along the x axis. Thus it is possible to tom jones plot start the elizabethan, iteration loop.

This is necessary since there are two contributions to mild steel yield strength the electric potential: the accelerating voltage (usually. ''2000 V) of the ion lens and the space charge of the ying particles. Era Foods. As this second factor depends on the particles trajectories, which in turn are determined by the total electric potential, an iterative approach has been adopted. The number of iterations can be set in the beginning of the code: const uint n _iter = 21 Then the i index spaces in the range 0 niter in order to reach the convergence. In the following a brief explanation of the operations executed in every cycle is provided: i = 0 : In the rst iteration the electric potential is calculated taking into account the electrodes contribute only, i.e. for = 0. After computing the electric eld, particles are sent. i = 1 : As particles are now present, space charge is calculated and set as a variable in the plasma model; in fact, with IBSimu, plasma is a function of space charge , electron temperature Te and plasma potential Up. Then electric potential (and subsequently electric eld) is bit and bridle, recalculated, now as a function of era foods, both electrodes and ying particles. As the charge density only changes passing from the rst to the second iteration, plasma is calculated only in this step; there is axolotl teeth, no need to recalculate it in the other steps. For i ' 2: The potential and eld are recalculated and era foods, so are the particle trajectories, until both electric potential and the tyger blake analysis line, space charge converge - i.e. until the era foods, dierence for these two parameters between two iteration is nearly zero.

There are dierent function to produce particles, depending on which beam parameters are known: 1. add_2d_beam_with_energy (uint32_t N, double J, double q, double m, double E, double Tp, double Tt, double x1, double y1, double x2, double y2) 38 2. add_2d_beam_with_velocity (uint32_t N, double J, double q, dou- ble m, double v, double dvp, double dvt, double x1, double y1, double x2, double y2) 3. add_2d_KV_beam_with_emittance (uint32_t N, double I, double q, double m, double a, double b, double e, double Ex, double x0, double y0) 4. add_2d_gaussian_beam_with_emittance (uint32_t N, double I, dou- ble q, double m, double a, double b, double e, double Ex, double x0, double y0) where N is the number of particles, J the beam current density (A/m2), q the charge of tom jones plot, beam particle (in multiples of e) and m the mass (u). For the rst two functions, the beam is elizabethan, dened on a line from (x1, y1) to axolotl teeth (x2, y2) and elizabethan, it propagates into a direction 90' clockwise from the direction of vector pointing from (x1, y1) to (x2, y2); at the beginning the beam prole is axolotl teeth, uniform. For the rst function E represents the era foods, beam energy (in eV ), while Tp and Tt are the parallel and transverse temperature, respectively, in eV. The particle speeds in direction i are sampled from a gaussian distribution with standard deviation dvi = p(Ti e/m), where Ti is the steel, beam temper- ature in elizabethan era foods, direction i (eV), e is the electron charge (C) and m is the mass of the ion (kg). With the third function, particles are own in the positive. x -direction from a starting location (center point) dened by (x0, y0) and the beam spread in the projectional space is made according to KV/hard- edged (Kapchinsky-Vladimirsky) distribution. I represents the beam total current (in A) and the tyger by line, Ex the starting energy of the beam (in eV). The beam is made to match Twiss parameters (a) and (b) in elizabethan, projectional direction (y,y'). The rms-emittance of the beam is made to match rms (e). After iterating trajectories (through a special object), electric potential and space charge are recorded in bit and bridle, the convergence.dat le; at the end of the simulation process this le can be found in the same folder where the source code is. If setted true in the beginning, it starts the last phase, the plotting one; this is the list of all the plots produced: ' particle traces in elizabethan era foods, the geometry eld; ' zoom of particle traces in the range 0 '' 1 mm (the zone including the skimmer and the focus point); ' electric potential as a function of x, usually a curve starting near 0 (the skimmer is tom jones plot, grounded but there is the plasma potential contribution) and ending at ''2000 V (the lens voltage); ' a 3D plot representing the electric potential as a function of x and y in elizabethan era foods, the skimmer region; ' emittance at f.r. leavis 50 mm, as a function of y and the angle y0, reporting the era foods, values of , , and ; 39 ' charge density (in C/m3) as a function of x; it is maximum at the beginning - at the skimmer tip -, then rapidly drops to bit and bridle zero, with a peak in correspondence to the focus point; ' space charge as a function of era foods, x and y in the skimmer region; ' kinetic energies (in eV) of ying particles, in a scatter plot, as a func- tion of particles mass; ' signal intensity, in arbitrary units, for each mass, at 8, 50 and 56 mm; ' beam prole histogram plot at 4 and 50 mm; ' a scatter plot for the beam prole, representing the y value as a func- tion of the particles mass, both at 50 and 56 mm.

40 Chapter 6 Simulation 6.1 Task 1 - solver. The rst task was to nd and compare the dierent available solvers, in order to bit and bridle nd out which one is the elizabethan era foods, fastest. With this aim, the computing time for blake, 1 and 2 iterations has been determined, using one thread only and considering an Argon beam with 20k particles, a beam current of era foods, 1 mA and a mesh size equal to 100 m. The outcome of this comparison is the bar plot in Figure 6.1. As it can be seen, the bit and bridle, UMFPACKSolver is the elizabethan, fastest. Moreover this solver can also use multi-thread; this feature makes the UMFPACKSolver the more suitable;1 accordingly, it was used throughout the entire project. 6.2 Task 2 - computing time vs mesh size.

As explained in the previous chapter, to calculate the electric potential and the charge density, IBSimu divides the simulation domain in small cells, with uniform size: for axolotl teeth, each cell UMFPACKSolver solves the elizabethan, problem, i.e. Poisson's dierential equation, and f.r. leavis, returns a value. So the mesh size has a large eect on elizabethan era foods, the quality of the approximation: the bit and bridle, smaller the mesh size, the elizabethan era foods, higher the quality of the simulation is (down to the limit of mesh_size '' 0, representing the exact solution of the Essay Compulsive Disorder, problem). The trouble is era foods, that it is impossible to decrease the mesh size innitely. The limits are the tom jones plot, available memory (with 8967201 nodes - equivalent to a 10 m mesh size - the system reports a memory allocation error) and the computing time. In fact, the higher the elizabethan, number of the tyger, nodes, the longer is the time needed to solve the problem. So it is useful to nd a compromise to solve the problem with a good approximation and in a relatively short time. The relation between computation time and mesh size was investigated for mesh sizes in the range of 15 '' 300 m.

In Table 6.1 and Figure 6.2 the data are given and plotted for a 20k particles Argon beam, with a current beam of 20 mA and 41 iterations. 1Twelve threads were available on the computer used. 41 Figure 6.1: Computing time for dierent solvers.

Bit And Bridle. It seems that the data points plotted have 2 dierent trends: the elizabethan, rst data can be tted with a root function, then (from the 50 m mesh) the data can be tted with really good approximation through a square function. The functions used to t the two curves are respectively y = a (1 + x) b (Figure 6.3) and y = A + B x + C x2 (Figure 6.4); (6.1) for the rst curve a = 0.32399, b = 0.59039, for the second curve A = 390.06724 , B = 6.03498 10''4 and C = 3.71075 10''10. As the tom jones plot, adjusted R2 are, respectively, 0.99772 and elizabethan era foods, 0.99998 these could be considered good ts. As explained before, the mesh size has an impact on tom jones plot, the quality of the era foods, results: a too large mesh could lead to a simulation not well representing the reality. In Figures 6.5 and axolotl teeth, 6.6 beam proles at era foods 50 mm for dierent mesh sizes are plotted; this trend has been used as judging parameter to test the quality of the steel yield strength, results. Elizabethan. A brief description of the beam prole evolution from the nest mesh to the coarser one is provided, comparing each one with the former. Because 15 m is the smallest mesh size that can be used, the 15 m prole has been taken as the plot which best represents the beam prole.

All the axolotl teeth, other plots, obtained increasing the mesh size, will be compared to this one. The main task is to reach a good compromise between the beam representation quality and the computing time: it is useful to elizabethan nd a minimum number of Compulsive Disorder, nodes which would guarantee a good nal result to attain the elizabethan era foods, time optimization. In the following (through a dierent geometry) the beam prole was tted with a nonlinear function, taken from the models 43 Figure 6.3: Fit for the rst six points plotted in Figure 6.2. Figure 6.4: Fit for the second part of the data plotted in Figure 6.2. 44 Figure 6.5: Beam proles for axolotl teeth, mesh sizes between 15 and 50 m. Figure 6.6: Beam proles for mesh sizes between 100 and era foods, 300 m. F.r. Leavis. 45 available in Origin. Before starting the analysis it is elizabethan, important to underline that every plot is symmetrical due to bit and bridle the applied geometry: the elizabethan era foods, code creates only the upper half of the simulation eld (i.e. the interfaces and the lens) and then it reects all the elements through a mirror function.

Considering the tom jones plot, rst four beam proles (mesh sizes from elizabethan, 15 to the tyger william blake analysis by line 30 m) one can note that there are no meaningful dierences: increasing the mesh size in era foods, this range the beam prole is unaected. As there are small dierences, the number of counts could be considered constant: the dierence between the 15 m and the 30 m plot counts is less than 0.2%. On the contrary, increasing the mesh size to 40 m, considerable dierences appear: even if the total number of counts is axolotl teeth, nearly equal, the curve clearly shows an era foods atypical evolution when approximating to the center. A sharp increase occurs in the very central range: the percentual dierence between the number of bit and bridle, counts at 0.25 mm and the one at 0.75 mm is about 22%. Further increasing the mesh size the result becomes more pronounced: the total number of counts decreases (till the dierence with the nest mesh is greater than 31% - for elizabethan, the 300 m mesh) and also the shape changes. In the 100 m plot there is a very high central peak (the ratio between this peak and the 15 m peak is more than 1.5), so the trend is already much dierent. Considering coarser approximations, the outer peaks trend becomes more uniform, while the central one broadens and then splits in two dierent peaks (in the 300 m histogram the central counts number is very low). In short, large mesh sizes produce unrealistic results and have to be avoided.

In conclusion the best compromise between quality and computing time is represented by the 30 m mesh. As it has been shown before, approxi- mately 22 minutes are requested for this geometry (for a 20k particles Argon beam with a current of 20 mA and 41 iterations). F.r. Leavis. Furthermore, the space charge density was calculated (data not shown). With increasing mesh size, almost nothing changes close to the skimmer orice. But a peak between. 0.01 and era foods, 0.02 m - where the beam is focused - decreases when larger mesh sizes, until it disappears at 50 m. The ratios between the peak height for three medium meshes, 30 m, 40 m and 50 m, and the smaller mesh used are 60%, 48% and 40%, respectively. Looking for a compromise, the former choice of a 30 m mesh size can be considered a good solution.

6.3 Task 3 - full 2D geometry switching. As the steel strength, 2D mirrored geometry could not be considered a good representation of the simulation area (some troubles arise for particles traveling on the x axis), the third task was to modify the code in order to dene a 2D full geometry. This conguration is era foods, not using the mirror function anymore, as the mild yield strength, interfaces and the lens are completely dened. After the switch to this new geometry, some simulations were run in elizabethan era foods, order to compare the new computing time with the former one. Table 6.2 shows the time for both geometries. It is important to underline that with the f.r. leavis, same mesh size the full geometry has a doubled number of nodes with respect to elizabethan the mirror 46 Table 6.2: Computing time for 2D mirror and full 2D geometry 2D mirror full 2D mesh (m) no of nodes time (s) no of tom jones plot, nodes time (s) time ratio 300 9956 77.85 24889 161.90 2.0 250 14336 97.61 35840 211.69 2.1 200 22400 131.92 56000 292.98 2.1 150 39822 163.45 99556 385.92 2.3 100 89600 259.35 224000 620.14 2.3 50 358400 619.59 896000 1493.79 2.4 40 560000 853.01 1400000 2164.20 2.5 30 995556 1343.57 2488889 4239.65 3.1 25 1433600 2021.08 3584000 7784.64 3.8 one, because the electrodes and the simulation eld are dened in the lower part too.

These values are referred to a 20k particles Argon beam, with a beam current of 10 mA and 41 iterations. The last column displays the ratio between the time taken by the full 2D geometry and the 2D mirror. The data ouput was used to evaluate the beam prole for the smaller mesh sizes (50 m, 40 m, 30 m and elizabethan, 25 m). The dierence between the full 2D and f.r. leavis, the 2D mirror beam proles gets obvious: they are no more com- pletely symmetrical, because particles are sent randomly. The member func- tion used in these rst simulations was add_2d_KV _beam_with_emittance(). It adds a 2D beam with dened KV emittance (KV stands for Kapchinsky- Vladimirsky, whose distribution is elizabethan, used for the beam spread in the projec- tional space). It becomes clear that the perfect beam symmetry could be achieved only with a large number of particles. Analyzing the f.r. leavis, number of counts in the two sections (the left and the right one) of era foods, each plot, it results that the percentual dierence is less than 1%; moreover the bias is anti correlated to tom jones plot the mesh size: 0.54% for 25 m, 0.45% for 30 m, 0.27% for. 40 m, 0.09% for 50 m. Era Foods. In order to compare the beam prole obtained with the two dierent geometries, one simulation with a 100k particles Ar- gon beam, with a current of 10 mA and a 30 m mesh size was used. The comparison with the corresponding 2D mirror result is displayed in Figure 6.7.

The dierences can be summarized in the following way: rst of all, even if the trend at the edge is similar, the midmost increasing is larger in the full 2D case. Moreover, the number of central counts is much higher in the full 2D case: the ratio between the peak heights is about 1.2 and the percentual dierence of the total number of counts between 2D mirror and full 2D curve is about 19%. This result shows the importance to switch to the new geometry; in fact it clearly proves that the mirror 2D case was aected by some errors in the trajectories calculation for particles in the center of the beam, the region we are mostly interested in. Finally, some attempts have been done to t the full 2D beam prole 47 Figure 6.7: 2D mirror - full 2D beam prole @ 50 mm comparison. (using the axolotl teeth, data obtained with the era foods, 30 m mesh) with a known distribution: as the Gauss t had a R2 adjusted of only 0.99134, it has been chosen a Lorentzian t, obtaining a better result (R2 adjusted = 0.9963). This t is displayed in Figure 6.8. William Blake Analysis. Olney, Chen and Douglas [30] measured gas ow proles downstream the skimmer using an era foods impact pressure probe. Bit And Bridle. It consisted of a small 0.254 mm diameter orice in a at plate at the end of a 6.35 mm od tube that was connected to a pressure gauge. The gas ow proles were measured for elizabethan era foods, an interface arrangement with a rst stage pressure (P1) of 3.3 Torr and a sampler-skimmer spacing of 6.4 mm; this interface is similar to that used on commercial ICP-MS systems.

Using French calculations [47], they found the density o the centerline: n(r, ') n0 = B cos 2 '' 2C r r0 ''2 (6.2) where ' is the polar angle between the centre axis and the point of interest, r0 the orice radius, r the distance of the probe from the source (r2 = x2 p +z 2 p , where zp is the distance of the probe from the mild steel yield strength, centerline) and B and C are, respectively, 0.643 and 1.365 (for Ar). The impact probe was scanned radially across the beam at 13 mm down- stream the skimmer; Figure 6.9 shows the elizabethan era foods, free jet gas ow prole obtained from impact pressure measurements made at several distances from the centerline. Considering the geometry and settings dierences between the case on study and the work by Olney, Chen and Douglas, the beam prole obtained with IBSimu is bit and bridle, consistent with the one shown in elizabethan, their work. 48 Figure 6.8: Lorentz t. Disorder. Figure 6.9: Free jet proles calculated - dotted line - and measured - lled circles; the era foods, density eld of equation 6.2 is multiplied by an additional factor. cos' to account for the decrease in bit and bridle, the apparent area of the elizabethan era foods, probe (solid angle) viewed from the source orice as the analysis, probe moves o-axis [30]. 49 6.4 Task 4 - Up and Te investigation. The optimum mesh size for a mirrored geometry was determined to be 30 m.

Since with a full 2D geometry the era foods, number of nodes doubles, some simulations have been done to see if a mesh bigger than 30 m guarantees good results. It has been found that using a 50 m mesh the beam prole does not change; so for the following task, this mesh size has been used. The aim was to analyze the eect of plasma potential (Up) and electron temperature (Te) on the beam prole. These parameters have been chosen because they dene the plasma itself and they represent the main contribu- tion to mild steel strength the particles trajectories. Elizabethan Era Foods. After few simulations it became clear that it was necessary to change the particle seeding function; we soon realized that add_2d_KV _beam_with_emittance() did not take into account the charge density and bit and bridle, it was initializing the plasma potential to a Null value (no dierences were seen varying the plasma potential). Era Foods. However, the beam proles calculated in the former task were correct, because with such a high current beam the space charge eect was signicant. So, the new used function was add_2d_beam_with_energy(), which adds particles with kinetic energies sampled from a gaussian distribution. Unfortunately, it was not possible with this new function to set a beam current greater than 5 A; for f.r. leavis, higher values, particles are grouped in bundles (needless to say that this result can not be true). So, with a 100k particles Argon beam, a current of 5 A and elizabethan era foods, 21 iterations (after having checked the con- vergence) some runs have been done with dierent plasma potential values: 0.1, 0.2, 0.5, 1, 2, 5, 8, 10, 15 and 20 V. The outcome beam prole does not have any signicative dierence until 1 V, then, increasing the plasma po- tential, the number of f.r. leavis, counts and the peak height decrease. Moreover, above.

10 V all plots are almost identical, both in elizabethan, shape and number of counts; as a consequence it does not make sense to investigate low or high intervals and the study was concentrated on the range 2 '' 10 V. This interval of survey is in bit and bridle, a good agreement with the available literature data [13][18][19]. Elizabethan Era Foods. The trend shown in Figure 6.10 is probably due to the space charge eect: it becomes more intense with a higher potential, especially in the center of the on Obsessive Disorder, beam, where the number of particles is elizabethan, high. So, increasing. Up, more and more particles are lost on mild steel, the skimmer walls; in a calculation for 10 V, this number could be near to 80% of the elizabethan, total number of starting particles. On Obsessive Compulsive. With a low plasma potential value, some particles are colliding on the skimmer wall too, but this number is smaller - with Up = 2 V it is about 40% - because the beam is spreading less than in the case of elizabethan era foods, high Up. Regarding the charge density plot, its trend does not change. Axolotl Teeth. The only dierence is in the peak corresponding to the focus point: its height halves from 2 to elizabethan era foods 6 V and then remains constant until 10 V. In conclusion of the plasma potential evaluation, one can say that the sharpest beam proles are achieved at lowest potential, in particular at bit and bridle Up = 2 V. A similar study has been conducted for the electron temperature, be- tween 2000 and 8000 K (corresponding to 0.259 and 1.035 eV, respectively, using the elizabethan era foods, equipartition theorem). Blake. The number of publications inquiring this 50 Figure 6.10: Beam proles for Te = 5000 K and era foods, dierent plasma potentials. topic is considerable [18][26][32][35][36]; the reported values range between. 1000 and 16000 K, depending on bit and bridle, many factors (distance from the era foods, load coil, radial position, dry or wet plasma, introduced analyte and mild yield strength, radio frequency power setting). The results for dierent plasma potentials (summarized in elizabethan, Figures 6.11 and 6.12) show a dierent behaviour. At low Up, increasing the bit and bridle, electron temperature results in a rise of elizabethan, counts at the boundaries and a decrease in the center.

Probably due to a greater thermal agitation, the beam prole becomes smoother (this attening is more uniform than the one obtained increasing Up). On the contrary, if the potential is high the plot is already at and by Essay on Obsessive Disorder, varying the temperature nothing changes. Era Foods. The best solution would be having a sharp peak (like the one obtained for the lower temperature) with a high number of counts (as it happens for axolotl teeth, high Te). So choosing the era foods, best electron temperature is not easy: both 2000 and 8000 K could be considered good solutions. In the charge density plot, increasing the electron temperature, the peak corresponding to the focus point moves slightly toward the skimmer, while its intensity increases and strength, the full width half maximum (FWHM) gets smaller. Era Foods. These changes are small, so they could be neglected. The best conguration would be a focus point far away from the skimmer, in order to minimize the space charge eect. Bit And Bridle. In order to better understand how the plasma potential and the electron temperature aect the simulation and, above all, to nd the combination that gives the best result, three 3D plots have been done, representing the total number of counts, the peak height and the FWHM as a function of the two fundamental parameters. The results are depicted in elizabethan, Figures 6.13 51 Figure 6.11: Beam proles for tom jones plot, Up = 2 V and dierent electron temperatures. Figure 6.12: Beam proles for era foods, Up = 6 V and dierent electron temperatures. F.r. Leavis. 52 Figure 6.13: Number of counts as a function of era foods, Up and Te. to 6.15.

As evaluated before, it was shown that Up = 2 V is the bit and bridle, best plasma potential. Regarding the electron temperature, two dierent values could be good: with Te = 2000 K the peak is narrow (lowest FWHM) and his height is maximum. On the other hand, with Te = 8000 K there is still a good FWHM and the number of era foods, counts is increased. The good quality of these two combinations (Up = 2 V - Te = 2000 K and Up = 2 V - Te = 8000 K) is underlined in the plot represented in bit and bridle, Figure 6.16, obtained with a combination between number of era foods, counts and FWHM. From the literature review it can be postulated that 2000 K is a too low value for the present case.

In fact the electron temperature in a Fassel torch is around 10000 K and the plasma bulk properties remain unchanged as it proceeds through the analysis line by line, sampling orice [19]; the only signicant electron loss at the walls of the sampling plate is conned to distances of the order of one Debye length - 10''2 to 10''3 mm. Elizabethan Era Foods. In conclusion for the next simulations the mild yield, following values were adopted: Up = 2 V and Te = 8000 K. Elizabethan Era Foods. 6.5 Task 5 - dierent masses. Once completed the tom jones plot, Argon beam simulations, the next step was to intro- duce other particles, to see the particles beam prole. Elizabethan Era Foods. Since the plasma is constituted by Argon, the number of the other masses is so low that their contribution to the electric potential is nearly negligible. So, to f.r. leavis speed up the simulation, it was convenient to simulate only Argon in the rst runs 53 Figure 6.14: Peak height as a function of era foods, Up and Te. Figure 6.15: Full width half maximum as a function of Up and Te. 54 Figure 6.16: (number of counts)2 / full width half maximum. (to calculate the tom jones plot, resulting electric potential) and then, in the last part, all the other particles. Elizabethan Era Foods. This topic will be discussed in detail in axolotl teeth, the next section.

The rst set of simulations was aimed to study how the number of counts is aected by era foods, the mass of the projectile at dierent potentials. The array of particles used (excluding Ar) was: 1, 5, 10, 20, 30, 50, 60, 80, 100, 140, 180, 220 , 260, 300 amu. 100k particles per species were seeded, with a 50 m mesh, Te = 8000 K and for dierent plasma potentials: 2, 3, 4, 6, 10 V. F.r. Leavis. The signal intensity per era foods species, downstream the f.r. leavis, lens orice, is given in Figure 6.17. The trend obtained is logarithmic for era foods, each potential, even if with in- creasing Up the curves are attening. A good t has been found: the curve.

y = a''bln(x+c) always provides R2 adjusted greater than 0.999. Compar- ing the plot in Figure 6.17 with the one obtained at 50 mm (just before the lens orice) and shown in Figure 6.18 clearly indicates that a lot of yield strength, particles are lost on the lens walls, as the maximum intensity halves. Moreover, the most intense lost is for low mass particles: considering the intensity ratio between 50 and 56 mm, it passes from 7.57 for m=1 to 3.87 for m=100 to 2.08 for m=300. Era Foods. This could mean that lower masses are mostly at the boundary of the beam - whilst higher masses are in the centre - or that the spread is higher for william blake analysis line, light particles - making the prole nearly at. In the following this particular distribution was studied through the beam prole plots. Era Foods. Considering instead the signal intensity per the tyger analysis line by line species for dierent electron temperatures, the curves are not aected and the intensity dierence is era foods, nearly negligible (see Figure 6.19). Increasing the bit and bridle, electron temperature, the 55 Figure 6.17: Signal intensity per mass @ 56 mm for Te = 8000 K and dierent plasma potentials.

Figure 6.18: Signal intensity per mass @ 50 mm for Te = 8000 K and dierent plasma potentials. 56 Figure 6.19: Signal intensity per mass @ 56 mm for elizabethan era foods, Up = 2 V and dierent electron temperatures. number of william blake analysis line, counts also increases, in a non linear way: higher the mass, bigger the dierence from two dierent temperatures is. Nevertheless the gap is quite small: for elizabethan, m=300, the percentual dierence between 5000 and 12000 K (in respect to the lower Te) is about 6. The eect of an electron temperature changing on the number of counts for m=300 is shown in Figure 6.20. In order to see in axolotl teeth, detail how plasma potential and electron temper- atures aect the beam prole, some simulations have been run with the three masses (in addition to elizabethan Ar) which give an overall view on all possible particles: 1, 150, 300. The result is consistent with the one obtained in case of Argon: it validates 2 V as the best plasma potential and the trend for dierent Te is equivalent to the one showed in the previous section. As it resulted from signal intensity plots, the bit and bridle, number of elizabethan era foods, counts for tom jones plot, lower masses is low. Running the same number of particles would make a comparison between beam proles of mass 1 and 300 impossible: the former one would be completely at compared to the other. As the beam prole evolution (changing Up and Te) is the same for mass 40, 150 and era foods, 300, it is steel yield, reasonable to presume this trend is identical for mass 1. The beam prole was studied in detail for dierent electron temperatures (Figure 6.21). Elizabethan. As it is shown for m=150, increasing Te, the central peak decreases and f.r. leavis, broadens until 6000 K, then, it starts increasing again. Moreover, while its central width does not change, the boundary number of counts progressively decreases and so the elizabethan era foods, transition from the boundary to the centre becomes sharper (the area under the curve being constant). The only dierence with 57 Figure 6.20: Signal intensity @ 56 mm for m = 300 and dierent electron temperatures.

Figure 6.21: Beam prole @ 50 mm for Up = 2 V, m = 150 and Essay Compulsive Disorder, dierent electron temperatures. 58 Figure 6.22: Beam prole @ 50 mm for era foods, dierent masses, for Up = 2 V and. Te = 8000 K. argon is right in this area: in the analyzed case the boundary number of counts drops to zero (this feature is even more noticeable for m=300) at about 4 mm from the centre, giving to the prole a more sharp shape. This phenomenon has been more deeply investigated. With a set of projectile similar to the one used for the rst plots, the beam prole for bit and bridle, each species has been represented - for Up = 2 V and. Te = 8000 K. For low masses it was necessary to run more particles in order to have a good statistics. Especially in this plot the mass discrimination is obvious: most of the low species are lost on the skimmer and elizabethan, lens walls, so their contribute is f.r. leavis, about one order of magnitude smaller for high masses. As observed before the beam prole progressively changes: while Argon (previously studied) can be tted with a lorentzian curve, increasing the mass, the prole loses its tails and acquires a better dened shape.

Starting from m = 160, the boundary number of era foods, counts drops to Essay zero; in other words, high masses are well focused. This is an important result, because it means that all these particles will pass through the lens orice. To better visualize the results it was convenient to represent the beam prole ratio between a given mass and mass 120. This value was choosen because its curve is the rst having nearly zero counts at the edge. Elizabethan Era Foods. As in the analyzer enters just the central part of the f.r. leavis, beam, high boundary ratios were not take into account. The plot in Figure 6.23 clearly shows the era foods, mass discrimination as a function of atomic mass and radius (radial distance from the beam center - dened as 0.02 m). Bit And Bridle. This plot underlines how much sharper the beam proles are for elizabethan era foods, high 59 Figure 6.23: Counts ratio @ 50 mm for Up = 2 V and Te = 8000 K. masses: it is important to notice that the resulting hollow for axolotl teeth, low masses does not mean the total number of counts in the center is lower than at the boundaries, but just that the number of counts is increasing slower (to the centre) for low than for high masses. 6.6 Task 6 - iteration settings. As anticipated, with many projectiles it is convenient to split the iteration phase in era foods, two parts: in the initial runs only Argon is seeded, while in the last all the other particles (dened in the masses array) are added. In fact the one that contributes more to the total electric potential is Argon, while other particles have a negligible impact on it. Some simulations have been run to answer the following questions: ' With a xed number of iterations, does the beam prole change vary- ing the the tyger william by line, number of initial and nal iterations' How' Is the computing time aected' ' How many particles are needed to y in the last run(s) in order to have a good compromise between a good beam prole and a short computing time' ' How many particles are optimal for elizabethan, the rst runs' The rst comparison was aimed to see which changes occur when the number of william blake by line, iterations in which all particles are sent vary.

With a xed 60 Figure 6.24: Electric potential dierence as a function of iteration number for the analyzed cases. number of total iterations (25), dierent combinations have been tried: (case 1) 10+15, (case 2) 15+10, (case 3) 23+2, (case 4) 24+1. The rst parameter checked was the electric potential convergence: in Figure 6.24 the electric potential dierence is shown for the considered cases. There are two points that have to be underlined: (i) the elizabethan, y axis has a logarithmic scale - this means that the initial decrease is mild steel yield, sharp - and era foods, (ii) in case4 the electric potential dierence is not calculated after ying all parti- cles - because in the code the particles are sent after the electrical potential is recalculated. 2 The increase in each curve is the tyger by line, due to the addition of other species: considering that the total electric potential is 2000 V, this oper- ation does not signicantly aect the result. To validate this hypothesis, the obtained beam proles have been compared to the one obtained in elizabethan, the rst case.

With 15 + 10 iterations the result is identical (exactly the same number of axolotl teeth, counts per interval) to the rst one, while case 3 and 4 have some small dierences, even if the prole shape remains unchanged. Elizabethan. As the com- puting time decreases from bit and bridle, 34 (case1) to 29 (case2) to 19 minutes (case4), the conclusion is the following: reducing the era foods, number of nal iterations does not signicantly aect the nal result; the dierence is negligible in all cases even for particles with low mass - in which case the total number of counts is low. This result has been validated also in axolotl teeth, the case of 20k particles in the rst runs and 100k in the last one. Then, two simulations with a dierent nal number of elizabethan era foods, particles have been performed: 50k and 100k. For low masses (m=1 in the analyzed 2So case4 represents the convergence for Disorder, Ar only. 61 Figure 6.25: Ratio between the beam prole @ 50 mm with 50k particles and elizabethan, the one obtained with 100k particles, for m=1. case) the number of particles reaching the end of the simulation eld is mild yield, low and random uctuations aect signicantly the beam prole. As the uctuation amplitude does not change passing from the rst to the second case, the former one represents a coarse approximation (as clearly indicated in era foods, Figure 6.25). Increasing the atomic mass the number of counts increases too and the background noise becomes negligible. Tom Jones Plot. So it is better to split the following discussion in two cases. For high masses the era foods, solution is likewise the prece- dent: running with 50k instead of 100k particles is a good approximation and the advantage is tom jones plot, that the simulation time is era foods, reduced - halved in the case of 10 + 15 iterations.

To see how much time is earned running less particles in the last run only, two simulations have been done, with 50k particles at the beginning and 50/100 in mild steel yield strength, the last run. The dierence is about 15%, but is not really signicant as the total time needed is around 20 minutes (19 min in the rst case and 22 min in the second). The situation is critical for low masses: running few particles in the last run(s) does not provide a good statistics. Therefore, it is convenient to run more particles (in the last run only), even if it takes a bit more time, to elizabethan era foods have a better statistic. To conclude this study, the last parameter to change was the number of particles in the rst runs: 3 the simulation result for 20k particles was compared to the one obtained for 50k - with 100k particles in the last runs 3A variation in bit and bridle, the number of era foods, Argon particles does not change the total charge density (it is Disorder, dened as constant); the only quantity changing is the charge density carried by each particle. 62 - rstly for 10 + 15 and then for 24 + 1 iterations. In both cases there are no dierences between the elizabethan, two simulations - for Essay on Obsessive Compulsive, the case 10 + 15 iterations every single beam has the same amplitude as in the other case and similarly for 24 + 1 iterations. In the elizabethan era foods, rst case even the computing time does not importantly change, probably because the time needed to seed only Argon is smaller compared to the one for f.r. leavis, all particles.

On the contrary, the dierence is notable in the second case: instead of 22, just 14 minutes are needed. Anyway, it is important to underline that this is elizabethan era foods, not a general result: sending more species, the time needed for the last iteration will increase, while the time for Argon does not change. So the percentual time earned will decrease with the total number of species increasing. Anyhow decreasing the number of Argon particles does not aect the beam prole quality, so it can be reduced to 20k. The following list summarizes the settings that optimize both the results quality and the computing time: ' number of iterations: 24 + 1; ' number of particles in the last run: 100k; ' number of particles in the rst runs: 20k. 6.7 Task 7 - Cadmium. In order to compare between simulation and experimental results, Cd can be used, with three of its isotopes: 110, 111 and 114. Through this com- parison it is possible to nd out the plasma fundamental parameters that characterize the used instrument. In the following a short experimental description of the implantation and measure of ions number is given.

In order to Essay on Obsessive Disorder detect the era foods, radial distribution of tom jones plot, Cd - this element is used because it shows a signicant radial dependence -, an Aluminium target was placed at era foods the base of the extraction lens. Thus implanted ions should represent the spatially resolved composition of the extracted ion beam. The target is analyzed by Laser Ablation ICP-MS after implantation, performing a line scan from the rim region (A) toward the center of the target (B), as shown in Figure 6.26. The spacing between two adjacent ablation spots (150 m) is sucient to have a high spatial resolution density and, in the same time, to avoid overlapping [43]. Because laser ablation removes material in the range of several hundreds of nanometer per f.r. leavis pulse, a complete removal of the im- planted ions is elizabethan, ensured. The calculated ratio 114Cd/111Cd in axolotl teeth, a single data set from a representative Cd isotope ratio analysis is elizabethan, represented in tom jones plot, Figure 6.27, with the era foods, corresponding transient signal for 114Cd. Since laser ablation provides spatially resolved information on the im- planted matter, a relation between Cadmium signal and ion beam intensity has to be assumed in order to deduce the f.r. leavis, ion beam prole. However, the sputtering due to the high Ar-beam current jeopardizes this relation; the 63 Figure 6.26: Sketch of the Al target assembly mounted in the Neptune MC- ICP-MS instrument. The dotted line denes the area exposed to the ion beam and era foods, the position of the line scan is given by mild steel strength, the black line [43]. Figure 6.27: 114Cd/111Cd isotope ratio (open circles) and signal intensity [43]. 64 Table 6.3: Set of simulation run run number Up (V) Te (K) 1 2 8000 2 3 5000 3 4 10000 4 8 5000 5 2 5000 6 2 10000 signal intensity is high in an annulus around 1 mm from the centre and then decreases when moving toward the centre.

This drop coincides with optically observed material defect; at this location the elizabethan, low signal is Essay Compulsive, probably caused by removal of material by sputtering. To plot the ratio 114Cd/111Cd against the distance from the centre, some simulations have been run, with the following conguration set: ' 35 iterations, 20 with Argon only + 15 with all the particles, ' masses array = 110, 111, 114, ' beam current = 5 A, ' mesh size = 50 m, ' dierent plasma potentials (Up) and electron temperature (Te). As explained before, the aim of these simulations was to nd a beam prole as similar as possible to era foods the one shown in on Obsessive Disorder, Figure 6.27. To reach this achievement, Up and Te were varied in their validity interval. The parameters for each run are summarized in Table 6.3. Beam proles have been plotted; increasing Up the trend becomes at, so Up = 2 V is the setting that resembles the real value best. Regarding the elizabethan era foods, electron temperature, its contribute is not signicant as the Up is. Since the ratio obtained with the simulation is slightly dierent from the experimental one, identifying the electron temperature real value results more dicult. Bit And Bridle. In Figures 6.28 to 6.30 ratios are given for three values of elizabethan, Te. It seems that the mild steel strength, intermediate case - 2 V and 8000 K - is the closer to elizabethan reality, even if the shape diers for some features.

While the bit and bridle, experimental plot rapidly decreases in the center and its trend is clear, the simulated one decreases slowly; at the edge, it can be seen the same low point it can be found at 6 mm in Figure 6.27 - even if in Figure 6.29 is at dierent position, 2 mm closer to the center. Era Foods. The trouble is that data processing could give rise to dierent explanations, depending on which bin size is choosen plotting the histogram. More accurated and resoluted simulations are necessary in order to make this comparison more precise and reliable. 65 Figure 6.28: 114Cd/111Cd ratio for axolotl teeth, Up = 2 V and elizabethan, Te = 5000 K. Figure 6.29: 114Cd/111Cd ratio for Up = 2 V and Te = 8000 K. 66 Figure 6.30: 114Cd/111Cd ratio for Up = 2 V and Te = 10000 K. 67 Chapter 7 Results and discussion The present work wants only to be a starting point in the understanding of the extraction process: in the future, on one hand more simulations and with dierent softwares can be performed and on the other some im- provements can be applied to the instrument.

IBSimu already represents a better simulation package compared to SIMION; with the latter, taking into account the tom jones plot, space charge eects is era foods, dicult and really impractical. Nev- ertheless, IBSimu still has a liability: it is impossible to y neutral particles and then simulating the scattering process between neutrals. Tom Jones Plot. For this rea- son the group of Kivel is elizabethan era foods, developing new simulations, both with dsmcFoam1 and with PI-DSMC (Parallel Interactive Direct Simulation Monte Carlo). Both this programs use the probabilistic (Monte Carlo) simulation to under- stand the uidodynamics of the free jet expansion. DSMC has been already documented in tom jones plot, some articles [38] [39]; the particular implementation of the algorithm is called FENIX. As the solver in IBSimu, the era foods, Monte Carlo al- gorithm models the gas ow by dividing the simulation region into f.r. leavis, small spatial collision cells, each one smaller in the extent than the local mean free path. Then, each particle is elizabethan era foods, given a random chance to collide with its nearest neighbor in its collision cell, using the collision statistics appropri- ate to f.r. leavis the density and temperature in the cell. Elizabethan. A more detailed description of the algorithm can be found elsewhere [38] [39]. The aim of the bit and bridle, FENIX simulation would be to make a more detailed calculation of the ow in the ICP-MS, not limited to the region downstream the skimmer anymore, but in the whole extraction interface. In this approach the study of the jet ex- pansion reported in chapter 4 is elizabethan, fundamental to steel make a comparison between simulated and theoretical results and in order to validate the model. Era Foods. This new simulation software is fundamental even for another reason: applying a modest voltage to the skimmer could improve the transmission eciency.

Usually about 10% of the total number of ying particles is lost on the skimmer walls and the trouble is that most of these particles are the lightest. Electrically oating one or both the cones at the tyger analysis by line various potentials could accelerate the ions and therefore reduce this phenomenon. It has been found, with IBSimu, that having the skimmer at few volts would focus the 1dsmcFoam is part of the open source CFD package OpenFOAM. Elizabethan Era Foods. 68 Figure 7.1: Sketches of the three used arrangements [23]. beam; the downside of this action stands upstream the skimmer, where ions would see a repulsive force. Axolotl Teeth. For this reason simulating the entire extraction interface with DSMC is necessary, in order to understand the beam behav- ior. Hu and Houk [23] applied modest DC voltages (+10 to elizabethan era foods +50 V ) to both the sampler and axolotl teeth, the skimmer or, alternatively, left the sampler oating - i.e., deliberately not connected to any voltage source or to ground - with the era foods, skimmer biased. Three specic arrangements (shown in bit and bridle, gure 7.1) were studied: (a) sampler and skimmer biased together, (b) sampler oated and skimmer biased and (c) sampler grounded and skimmer biased. The results are depicted in era foods, gure 7.2 with Co+ as analyte.2 There is an improvement in each case: by axolotl teeth, a factor of 4 (modestly) by applying the same DC voltages - about 20 V - to both sampler and skimmer (A), by a factor 5 of in case C, and by a factor of 6 by oating the sampler and elizabethan era foods, applying a DC voltage of 30 '' 40 V to the skimmer. Tom Jones Plot. It results that conguration b is the one which gives the era foods, higher signal; 2Relative sensitivity refers to the sensitivity obtained for a given element with one of the Compulsive, new interface arrangements divided by that obtained for elizabethan, the same element with the conventional interface. 69 Figure 7.2: Relative Co+ sensitivity as a function of biasing voltage [23].

Table 7.1: Molar sensitivities for steel, various elements expressed in era foods, terms of atomic concentration [23] molar sensitivity (counts/ (s mM)) interface arrangement Co Rh Ho m/z = 59 m/z = 103 m/z = 165 conventional interface 5.6 107 8.5 107 2.2 108 interface b 3.5 108 3.3 108 3.0 108 in Table 7.1 molar sensitivities for various elements are compared. Another advantage given by this conguration is the reducing of the mass bias: in fact, the sensitivity is improved for Co+ by a much greater factor than is in the case for the heavier Ho+. Even if it seems that the tom jones plot, ions have a sucient kinetic energy to ow through the sampling cones, some simulations should been run in elizabethan era foods, order to check what happens upstream the mild, skimmer: applicating a positive potential could repel ions and elizabethan era foods, prevent them from passing through the orice. So in this case the f.r. leavis, simulation eld has to elizabethan era foods be extended, in order to start the beam in Essay on Obsessive Compulsive, correspondence to the sampler. 70 Chapter 8 Conclusions As explained in the introduction, the aim of this work was the optimization of the ion extraction from the ICP.

IBSimu turned out to be a suitable and era foods, useful instrument for this purpose, thanks to its versatility and easiness of use. It calculates the comprehensive electrci potential dividing the simula- tion region in analysis line by line, small meshes or cells. Once chosen the era foods, fastest solver among the many available, the mesh size has been determined in order to have a good compromise between results quality and computing time. At the beginning, the code describing the simulation eld was characterized by a 2D mirror geometry; due to some problems, switching to a full geometry came out to be convenient. Then the main section of the work started: the investigation on how the beam prole changes upon varying the plasma main parameters, i.e. the plasma potential and the electron temperature. Changing the on Obsessive, plasma potential, noticeable dierences were observed in the beam prole only in elizabethan, the range between 2 and 10 V; increasing Up more particles collide on the skimmer wall and then the tom jones plot, beam prole decreases in intensity attening. The electron temperature has a less considerable eect and, particularly, its consequence depends on the plasma potential value: if Up is elizabethan, low, increasing. Te the trend attens, while if Up is high nearly nothing changes.

Since the blake analysis, aperture to the mass spectrometer is 4 mm wide, the couple of values. Up = 2V and Te = 8000K has been chosen in elizabethan era foods, order to have a sharp peak with a high number of f.r. leavis, counts. This result has been obtained ying only Argon ions, but it has then been ratied simulating a beam with many species. One of the most severe problem in the Inductively Coupled Plasma Mass Spectrometry is elizabethan, mass discrimination, that is the yield, preferential lost of the beam particles with a low mass in respect to heavier species. Elizabethan. This phenomenon has been characterized and then the eect of a plasma potential and elec- tron temperature variation has been studied in order to see if it determines any advantage.
