Mechanism of the high effective generation of electron beams in high-voltage discharge in helium and its mixtures with oxygen and nitrogen

The results of the studying the current-voltage characteristics and the efficiency of generation of electron beams in continuous discharges in helium, its mixtures with oxygen and nitrogen, and also in pure oxygen and nitrogen are presented. The characteristics of the current-voltage characteristics, which explained from the point of view of the change in the role of the main mechanisms of electron emission with increasing voltage, are noted. It is shown that a high value of the efficiency of electron beam generation above 80% can be obtained in glow discharges in helium, oxygen and nitrogen. In helium, it is provided by the predominance of photoemission, in oxygen and nitrogen, or their mixtures with helium mainly kinetic emission under the action of fast heavy particles.
