Improving estimation of rising time of High Voltage Glow Discharge current in triode electrodes systems with taking into account changing of anode plasma parameters

The estimations for electrons temperature and mobility in anode plasma of High Voltage Glow Discharge (HVGD) in condition of lighting the additional discharge are given in this paper. These estimations are based on the theory of interactions between the discharge plasma and electron beam. Obtained theoretical estimations are very important to precision valuation the time of discharge current increasing in the impulse regime of gun operation.
