PLASMA PRODUCTION PROCESS Russian patent published in 1997 - IPC

FIELD: high-voltage engineering; plants for generating heavy-power bremsstruhlung pulses and electron beams. SUBSTANCE: plasma is produced by means of electric discharge on dielectric surface where to high-voltage triggering pulse is supplied followed by time-regulated application of working pulse. Used as triggering pulse is working-voltage pre-pulse across accelerating tube cathode formed due to capacitive couplings between tube and voltage supply during working pulse shaping. Plasma parameters and time of its generation relative to arrival of working pulse are controlled due to variation in relations between capacity formed by cathode and intermediate electrode and capacity formed between intermediate electrode and anode, as well as due to variation in capacity between accelerating tube and voltage supply. EFFECT: facilitated procedure. 3 dwg
