A multi-group electrodes and multi-pulse high power gas switch

A switch with three groups of electrodes was developed. The feasibility of the concomitance of multi-group electrodes, the switch structure and the internal electric field were analyzed. The current through the switch was calculated using the software Pspice. When a couple of electrodes of this switch are in operation, the voltage is about 50kV, the current is above 100kA, and the pulse width is around 20μs. When three triggered pulses of 1ms interval are fed in three trigger poles of the switch respectively, the switch can produce three 1ms interval pulses through the inductance load, each has the voltage of 38kV, current of about 100kA and width of about 20μs.
