FIELD: electron beams generation.
SUBSTANCE: invention relates to the field of generation of electron beams of large cross section. A method for improving the energy efficiency of electron sources based on ion-electron emission with beam output to the atmosphere consists in using an electron source based on a non-self-sustained high-voltage glow discharge, the auxiliary glow discharge plasma is generated in a repetitively pulsed mode with a frequency of up to 100 kHz with the possibility of combustion duty background low-current discharge, and the amplitude of the auxiliary discharge current is changed by changing the duty cycle of the pulses in the range of 0.1-0.9.
EFFECT: increasing the efficiency of generation and extraction of an electron beam from a vacuum into the atmosphere or a volume of high pressure by using a repetitively pulsed high-frequency auxiliary glow discharge.
