Abstract
The article proposes an iterative technique of calculation of energetic efficiency of triode high voltage glow discharge electron sources’, based on taking into account the influence of heating of anode plasma by the accelerated electrons of electron beam and by the slow secondary discharge electrons, reflected from the anode. The increase of temperature of anode plasma influences its’ volume, as well as the concentration and mobility of ions’ in it. Therefore, the proposed model allows obtaining the corrected values of discharge current and energetic efficiency of electron sources by taking into account the thermodynamic parameters of anode plasma. In addition, one of the advantages of proposed iterative calculation technique is that the model is closed and self-consistent, therefore, it does not demand use of approximated data about the thermodynamic parameters of discharge plasma from references.
