Normal glow discharge in axial magnetic field
Abstract
Theory and results of mathematical modeling of a glow discharge in a parallelplate configuration with axial magnetic field is presented. The model consists of continuity equations for electron and ion fluids, the Poisson equation for the selfconsistent electric field. Numerical simulation results are presented for twodimensional glow discharge at various initial conditions. The results are obtained for molecular nitrogen at pressure 15 Torr, emf of power supply 12 kV, and magnetic field induction B = 00.5 T.
It is shown that in the presence of the axial magnetic field the glow discharge is rotated around its axis of symmetry. Nevertheless it is shown that in the investigated range of discharge parameters in an axial magnetic field the law of the normal current density is retained.
