Low-frequency processes in the bounded plasma with electron-ion collisions
D. S. Filippychev M. V. Lomonosov Moscow State University
Abstract:
The problem of the behavior of plasma, bounded by absorption wall in longitudinal direction is considered. Model contain charge particles (electrons and ions), moving under influence of self-consistent electrostatic field. New charge particle pairs are assumed to enter to system in non-local source region. The computational tool used for this study is the electrostatic “particle-in-cell” method, which is enhaned by the addition of Emmert model for non-local source and Monte Carlo binary collision model. Only electron-ion collisions are taken into account. Mathematical model is formulated. The methods for solution of partial problems, which compouse the algorithm for numerical modeling of considered system are described. Direct implicit method is used with large time step. The results of calculations are presented for various particle numbers on Debye length.
