Monte Carlo simulation of x-ray absorption and electron drift in gaseous xenon

A detailed Monte Carlo simulation model has been developed to study the absorption of soft x rays and the subsequent behavior of the resulting electrons under the inhuence of an applied electric field in gaseous xenon. All relevant physical processes are included from the initial photoionization through the subsequent decay of the residual ion to the scattering and drift of the electrons resulting from the interactions with the background gas. Details are provided for the cross sections and decay rates employed as well as the criteria used to terminate the simulation, depending on the information or results required. Examples of its use in modeling gaseous radiation detectors are included.PACS number(s): 32.80.t, 29.40.Mc, 29.40.Cs, 34.90.+ q

“…Above 100 eV the two data sets agree within the error bar. Several other excitation cross sections at selected energies have been published (see [29,30] for Ne, [31,32] for Ar, [33] for Kr, [34,35] for Xe). Nevertheless these data do not constitute a consistent body suitable for the present analysis.…”

Empirical analytical formulae are proposed, aiming at the description of partial cross sections for electron scattering on noble gases. Selected measurements of total, excitation and ionization cross sections for these gases have been fitted by these analytical formulae in the 20-5000 eV energy range. The elastic cross sections, obtained as the difference, compare quite well with the elastic experimental data for all gases but for helium. The difference elastic cross sections were fitted by a cross section formula derived from electron scattering on a single or double Yukawa potential in the first Born approximation. Our analysis shows a good consistency between partial and total cross sections for the four heavier gases. For helium, we suggest the possibility of large errors in the high energy part of total, elastic and excitation cross sections. The analytical expressions given in this paper allow to reproduce the total and partial cross sections within the measurement errors in a large energy range from a few tens of eV, up to several keV. PACS: 34.80.Bm; 34.80.Dp I IntroductionElectron-atom and electron-molecule cross section data are important in a large variety of applications and fields (see for instance [1]). In these applications, cross section values as a function of the energy are needed as input data in calculations, modelling and Monte Carlo simulations. Some examples can be found in [2] for plasma chemistry, in [3] for fusion plasma research, and in [4] for electron and positron slowing down and diffusion in solids. Many applications of electron impact ionization cross sections (from gas discharges to astrophysics and atmospheric physics) presented by different authors, are reported in [5].An obvious help to these computational works can be provided by analytical or empirical expressions describing the cross sections data [6][7][8][9]. Where these formulae are not available, tables of data and interpolations or extrapolations must be used. Analytical representation are also interesting by themselves giving direct information on the consistency of different data sets, and allowing extrapolation of cross section data at energies where experimental measurements do not exist. Moreover, some insight and information on the type of interaction can be gained. In our recent studies [10-13] we have measured the electron scattering total cross sections on three families of molecules in the 70-4000 eV energy range and described these cross sections from a few tens of eV to 4000 eV by a simple analytical formula using two or four adjustable parameters. In this paper we present a partitioning scheme for electron scattering on noble gases, where the total and the partial cross sections are approximated by analytical formulae.To date, a relatively large number of good quality electron scattering measurements on noble gases cover an energy range from less than 1 eV to 3000 eV. The works of de Heer and Jansen [14] on He, de Heer et al. [15] on Ne, Ar, Kr, Xe, present a comprehensive evaluation of semiempirical values...

“…Comparison of the present results with other available data can be briefly summarized as follows. Nishimura et al (1985Nishimura et al ( , 1994 and Filipović et al (1988) obtained DCS 1+2 (90 • ) values based on their measurements of scattering intensity ratios for excitation of these two levels and elastic DCS's (90 • ) values. Nishimura et al (1985Nishimura et al ( , 1994 used elastic DCS's (90 • ) measured in a separate experiment (Nishimura et al 1980) while Filipović et al (1988) used the elastic DCS's (90 • ) of Register et al (1980), Ester andKessler (1994) also obtained the DCS 1+2 (90 • ) values by an absolute measurement scheme.…”

An electron time-of-flight (TOF) technique was utilized to obtain absolute differential cross sections for electron impact excitation in He, Xe, N 2 and CO at near-threshold impact energies at 90 • scattering angle. These cross sections are more reliable that those obtained from conventional beam-beam scattering measurements using electrostatic spectrometers and can serve as secondary standards for normalizing relative scattering intensities. The results obtained from the TOF measurements are significant also because they fill the gap between cross sections available at very near threshold and intermediate impact energies.
