Theory of high-voltage glow discharge with the generation of a monoenergetic electron beam
Kinetic theory of high-voltage glow discharge (HVGD) is developed. The Poisson equation in the bulk charge layer is solved taking into account the flow of ions coming from the plasma into the layer, the ionization of gas in the layer by electrons, ions and fast atoms. On the cathode there is a potential and kinetic extraction of electrons from the surface. For different values of gas density and secondary emission factor, current-voltage characteristics is calculated, the volume charge layer dimensions are determined, the electric field distributions in the layer and other HVGD characteristics are obtained. The proposed mathematical model can be used to calculate the characteristics of electron accelerators based on HVGD.
