Abstract

The combined numerical and physical modeling of a glow discharge between plane disk electrodes in molecular nitrogen is performed at pressures р = 3 and 5 Tor. The satisfactory description of experimental data by the drift-diffusion model is shown. The simultaneous analysis of experimental and calculated data has permitted identification of the normal burning regime of a glow discharge. However, the essential effect of model parameters such as the secondary electron emission coefficient and the first Townsend coefficient on the calculated voltage-current characteristic has been demonstrated in this case.
