Abstract
Numerical simulation model of a Direct Current Discharge (DCD) in external magnetic field is used for analysis of behavior of normal DCD at the initial time instants after switching-on of transversal magnetic field. Numerical simulation results are presented for two-dimensional glow discharge at pressure 5 Torr, Emf of power supply of 2 kVolt, and magnetic field induction of B = 0.05 T. The model is based on the diffusion-drift theory of gas discharge consisting of continuity and momentum conservation equations for electron and ion fluids, as well as the Poisson equation for the self-consistent electric field. Feature of our approach is to calculate electron transport coefficients for diffusion-drift model by solving the electron Boltzmann equation. It is shown that the switching-on of transversal magnetic field gives rise to the DCD plasma oscillations. The plasma oscillations are observed also in moving DCD in perpendicular direction to applied electric and magnetic field.
