- Abstract
The paper studies the problems of mathematical simulation of triode high voltage discharge gap and defines its current-voltage characteristics. We obtain analytical relations to calculate current-voltage characteristics of triode high voltage glow discharge (HVGD) electron sources. The proposed calculation technique is based on analyzing charged particles balance in HVGD anode plasma taking into account the condition of self-dependence of its lighting. The model is very simple and universal. Basic model parameters are geometry dimensions of discharge gap, specifically the longitudinal length of anode plasma, which can be calculated analytically by solving the cubic equation. It is classified as physical-topology model and allows making preliminary theoretical estimations of energy parameters of HVGD electron sources at the pilot design stage. Divergence between calculations and experimental data is less than 15 %.
