TLDR
In this article, a model of the electron current in a plane plasma slab bounded by parallel dielectric walls in the presence of a homogeneous magnetic field perpendicular to the walls and an electric field oriented along the walls is presented.Abstract:
A model describing the phenomenon of the electron current in a plane plasma slab bounded by parallel dielectric walls in the presence of a homogeneous magnetic field perpendicular to the walls and an electric field oriented along the walls is presented. The current flows along the electric field because of the electron collisions with diffusely scattering walls. The model takes into account the presence of Debye layers and the non-Maxwellian character of the electron distribution function. Collisions in the plasma volume are ignored.read more

Plasma flow and plasma–wall transition in Hall thruster channel
TL;DR: In this article, a model of the quasineutral plasma and the transition between the plasma and dielectric wall in a Hall thruster channel is developed, where the plasma is considered using a two-dimensional hydrodynamic approximation while the sheath in front of the surface is considered to be one dimensional and collisionless.

Kinetic simulation of secondary electron emission effects in Hall thrusters
TL;DR: In this article, the particle-in-cell code has been developed for kinetic simulations of Hall thrusters with a focus on plasma-wall interaction, and it is shown that the effect of secondary electron emission on wall losses is different from predictions of previous fluid and kinetic studies.

Experimental and theoretical studies of cylindrical Hall thrusters
TL;DR: The cylindrical Hall thruster (CHT) is fundamentally different from the conventional design in the way the electrons are confined and the ion space charge is neutralized as mentioned in this paper, and the performances of both the large (9-cm channel diameter, 600-1000W) and miniaturized (2.6-cm Channel diameter, 50-300W) CHTs are comparable with those of the state-of-the-art conventional (annular) design Hall thrusters of similar sizes.

Michael Keidar,Isak I. Beilis +1 more
TL;DR: A review of plasma devices involving electron drift in crossed electric and magnetic fields (EtimesB drift) and electron transport phenomena is presented in this article, where a modified model of the near-wall conductivity that takes into account various sheath effects is developed.

Secondary Electron Emission
TL;DR: The theory of secondary electron emission under electron bombardment is completely different from that under ion bombardment; in the former case the bombarding particles penetrate into the solid, thus producing a bulk effect; the latter case one deals essentially with a surface effect as mentioned in this paper.
