In the present work a theoretical model considering the processes of generation and losses of charged particles in the cathode region of a glow discharge in the drift approximation for ion and electron motion is developed. Exact analytical solutions which can be used to calculate the current-voltage characteristics of the glow discharge in an arbitrary gas with the known Townsend ionization coefficient are derived. The calculated parameters of the normal glow discharge (the current density discharge burning voltage and width of the space charge region) for different gases are in good agreement with the available experimental data.
