The mathematical model of triode high-voltage glow discharge electrodes’ system with the plane additional electrode is considered in the article. The proposed model is based on defining the plasma boundary position on the base of solving cubic equation with taking into account the real electrodes’ geometry. The formula for recalculation of plasma boundary position from one-dimensional model to electrodes’ system with conic anode is obtained. The results of calculation of energetic efficiency for real parameters of electron gun are presented and analyzed in the article. Calculation results are compared with experimental data. Obtained accuracy of calculation, in comparing with experimental results, is nearly 10 – 15%.
