Abnormal Glow Discharge between Two Electrodes on Plane with Transverse Magnetic Field

Abstract

Abstract Surface glow discharge in the abnormal mode of its burning at pressure 5 Torr is numerically studied at a voltage drop of ∼650 V between electrodes, located on plate surface at a distance of 2 cm. The drift-diffusion two-dimensional model of gas discharge plasma is used for the description of electrodynamic parameters of the discharge. It is shown that external transverse magnetic field of induction about 0.2 T occurs significant influence on the gas discharge plasma configuration, squeezing or expanding electric current channel between electrodes depending on the magnetic field polarization. Two-dimensional fields of electrodynamic functions, such as the volume concentrations of charged particles, electric potential and the force lines of electric field strength without and with external magnetic field are presented and analyzed.
