“…Test runs of the code for primary electrons were performed with a large number of examples from the literature. Both isotropic and anisotropic models of Reid were used [7,42] and in all cases satisfactory agreement was achieved. In addition we compared our results for pure argon and nitrogen at moderate E/N with the Boltzmann equation calculations performed with identical sets of cross sections.…”

A code for Monte Carlo simulation (MCS) of electron motion adjusted to include boundary and non-equilibrium effects is developed, tested and applied to model low-pressure, low-current, moderate to very high experiments in nitrogen. It has the flexibility to include effects of anisotropy, non-conservative collisions, steady-state Townsend (SST) conditions and electron reflection and backscattering at the anode. The results of the simulation are compared with available experimental data such as spatial distribution of emission of first negative band in nitrogen, ionization coefficients and charge multiplication. Good agreement exists between the results of simulations and the experimental data indicating that the basic understanding of non-equilibrium development is available, while some differences point to the need to adjust the corresponding cross sections or models of scattering.

“…The cross sections of electron scattering from the CF 4 molecule play a significant role in the discharge electrodynamics. In recent years, a number of works has been published concerning the cross sections of various inelastic processes in CF 4 [14,15]. However, the cross section set from [16,17] has often been used in the modelling of CF 4 discharge (for example, in [5]).…”

The influence of non-locality and anisotropy of the electron distribution function (EDF), as well as of the non-equilibrium ion diffusion, on the behaviour of the discharge in a strongly electronegative gas has been studied using as an example a DC glow discharge at low pressure. In order to take into account the spatial non-uniformity of the EDF, we used the spatially dependent mean electron energy (MEE) method and the particle-in-cell Monte Carlo (PICMC) technique. The results of calculations were compared with the experimental values of the reduced electric field for the DC glow discharge. It has been shown that, for the case of low pressures (high reduced electric fields), the PICMC technique describes the discharge the most adequately. It has also been shown that the EDF is strongly anisotropic at low pressure, in which case the ionization process is supported by electrons moving in only one direction. The non-equilibrium ion diffusion (due to the ion-heating in the axial electric field) has been shown to bring about a significant modification of charged particle radial profiles. As a result, the region of quasi-neutral electron - ion plasma near the tube wall does not exist throughout the range of pressures studied (0.13 - 2.6 Torr).
