The paper presents results of computer simulation and experimental measurements of the concentration distribution of high-current non-self-sustained glow discharge plasma generated in the hollow cathode at low pressure. The simulation performed in the drift-diffusion approximation, allows to obtain the main dependences and properties of the glow discharge (current-voltage curves, distribution of the plasma concentration and potential) in a large-sized hollow cathode with two electron beam sources. Calculation results are in agreement with the experimental data.
