TLDR
In this paper, the electron distribution function for simple examples of a stationary discharge in a dc space charge field is derived for the case of positive columns and microwave discharges in inert gases.Abstract:
Calculations of the electron distribution function are presented for some simple examples of a stationary discharge in a dc space charge field. The treatment is valid when the predominant mechanism of energy exchange arises from motion in the dc space charge field. The computations indicate that the effect of dc space charge is, for a given external field strength, to increase the proportion of high energy electrons over that computed neglecting space charge. This results in a larger specific ionization rate, but the effect is not so great as to account for the low maintenance potentials observed in positive columns and in microwave discharges in inert gases.read more

Kinetic modeling of low-pressure nitrogen discharges and post-discharges
Vasco Guerra,P A Sá,J Loureiro +2 more
TL;DR: In this paper, the authors reviewed the kinetic modeling of low-pressure (p ∼ 1−10 torr) stationary nitrogen discharges and the corresponding afterglows and showed that a good description of the overall behavior of nitrogen plasmas requires a deep understanding of the coupling between different kinetics.

On simplifying approaches to the solution of the Boltzmann equation in spatially inhomogeneous plasmas
TL;DR: In this paper, the authors present simplified approaches to the kinetic description of the electron component in weakly ionized plasmas based on the direct solution of the Boltzmann equation in some limiting situations, namely the ''nonlocal" approximation in a weakly collisional plasma and the ''local'' approximation in an extremely collisional one.
