Abstract
The results of experimental studies of the fast electron distribution function under the conditions of a nonequilibrium plasma of a pulsed discharge in helium are presented. It is established using various methods that a beam of fast electrons, the energy of which depends on the voltage applied to the discharge gap and gas pressure, is generated at a helium pressure of 0.02–2.0 Torr in the initial stage of the discharge, when the reduced electric field strength exceeds the critical value.
