Pulsed hollow cathode discharge characteristics

Hollow cathode discharge is a type of glow discharge which occurs as a result of “hollow cathode effect”. One of many applications of pulsed hollow cathode discharges is high current closing switches. Pseudosparks utilize this type of discharge for the initiation of its discharge. Hollow cathode phase of a pseudospark discharge is the phase which is responsible for rapid current rise after triggering. Carrier multiplication at this phase is very high leading to good transition properties. In this work we designed an electrically triggered pulsed hollow cathode discharge scheme and analyzed its characteristics.
