Dynamics of electron-cascade formation in a pulsed discharge

The dynamics of the velocity distribution function of the electrons in a pulsed discharge is analyzed, taking account of the initial stage of electron heating within the framework of the BGK model integral. It is assumed that the basic contribution to the relaxation of the electron distribution function comes from elastic collisions with neutral particles. The dynamic distribution function obtained is used to determine the ionization coefficient and study the dynamics of electron-cascade development.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 5, pp. 70–75, May, 1984.In conclusion, Prof. V.
