Abstract :
An alternative mechanism for emission during the high-current phase of a pseudospark discharge is presented. A high current density is provided by multiple arc cathode spots which appear due to cathode-plasma breakdown. The model of plasma formation in the main gap of the pseudospark switch is discussed, together with conditions required for the initiation of spot during some tens of nanoseconds, the appearance of a moving double plasma layer, and high-current transport through the plasma-filled diode
