Abstract :
This paper deals with the investigation of the fast electron beams that form in the high-current pseudospark discharge at different stages of its development. Three short-duration peak of the beam current at the discharge axis have been revealed. The physical reasons for the appearance of these peaks of the beam are discussed. The main idea of the proposed physical mechanism is that the electrons are accelerated in a double electric layer, which forms between the hollow cathode plasma and the near-anode plasma.
