Abstract

Two-dimensional drift-diffusion calculation model of charged particles in a normal glow discharge between plane disc electrodes is presented. The verification of the created computational model has been performed using the experimental data on a normal glow discharge between flat electrodes with distance H=1 cm. Results of numerical simulation and initial experimental data are presented for the pressure of p = 5 Torr and emf of power supply in the region of 1000 ÷ 1750 V. The sensitive of the computational models to its internal half-empirical parameters are analysed on the example of volt-ampere characteristics.Introduction
