Abstract

One dimensional model of plasma bound by two nonconducting walls in external magnetic and electric field is developed. In particular it is designed to describe plasma in Hall thrusters. Combination of Particle-in-cell method with guiding centre approximation of electrons motion allows for kinetic description in short computational time. Comparison of plasma parameters done for two different secondary electrons emission profiles reveals insignificant influence of wall material on the condition in one dimensional model.
