Breakdown of accelerating gap of plasma electron source in fore-vacuum pressure range.
Investigations of electrical breakdown in acceleration gap of plasma cathode electron source are presented. The tested pressure range 0,01 -0,1 Torr is produced by only mechanical pumps. It is stated breakdown volt¬age decreases with emission current growth. The most probable reason is electric field growth because of ac¬celeration gap shortening as a result of plasma produc¬ing near accelerating electrode.
