“…For example, the increase in the speed of ionization waves (in argon, helium, and air) can be observed as the discharge develops. Such phenomena are widely represented in the literature, for example: [32][33][34][35]. Unlimited growth of streamers' velocities could compromise time-local BKE solutions which were used to determine reaction constants.…”

“…Calculation results were averaged and saved for each 10 ps. The range of reduced electric fields was chosen to cover the conditions for streamers from [34,35]. For electric fields below 2.5 kV cm −1 the initial size of the particles ensemble was 100000, and for higher electric fields initial size was 10000 (the latter is because of the rapid exponential growth of the ensemble due to ionization events).…”

In this paper, we examine the energy distribution function of electrons in the case of a very weakly ionizedargon plasma at sub-atmospheric pressure and external electric field using Boltzmann kinetic equation. We areinterested in the behavior of the collisional part of the equation, thus spatially uniform model is considered. Thegoal of the research is to compare two different numerical approaches: a deterministic one (using a two-term localnon-stationary approximation) and a stochastic approach (using the Monte Carlo method) over a wide range ofreduced electric fields: from several Td to kTd. We present the comparison for steady-state and time-dependentsolutions, isotropic and anisotropic parts of the electron energy distribution function, and reaction constants.The research will also help to identify any limitations and challenges of these methods.

“…Nevertheless, TTB is widely used to calculate the various types of gas discharges (streamers [33,34], glow discharges [35,36], sparks [37], DBD [38,39], corona discharges [40,41]), including in the near-electrode regions, where abnormally high electric fields and their gradients are. In this case, there is no opportunity to study the phenomena caused by the difference in longitudinal and transverse diffusion.…”

In this paper, we investigate the spatial-local electron energy distribution function (eEDF) interacting with a backgroundgas at the sub-atmospheric pressure in a wide range of applied crossed electric and magnetic fields using the Boltzmannkinetic equation. We compare solutions obtained using two numerical approaches (deterministic two-term approximation andstochastic Monte Carlo method) to identify their applicability in the context of determining drift velocity and reaction constantsfor electrons. For argon and helium, the upper limit of the reduced electric field applicability of the two-term approximationis discussed. It has been shown that the presence of a magnetic field can reduce this limit. Two explanations are given, oneis based on the math of two-term formalism, and the other is based on velocity-space analysis. Two-term approximation failsdue to it’s inability to resolve underlying cyclotron oscillation (it should result in an energy variation along the electron’strajectory). The absence of this feature causes an incorrect estimation of momentum-transfer rate. This results an inaccuracyin the estimation of the angle between electric field and drift velocity.
