Design of 5 kHz repetition-rate trigger for hydrogen thyratron

A trigger device is designed for the hydrogen thyratron VE4141 according to the trigger method of hydrogen thyratrons used in the repetitive pulse-power system, which can output trigger pulses of repetition rate up to 10 kHz. In addition, it can receive optical and electric trigger signals. The pre-trigger pulse and main-trigger pulse are produced by fast-edge MOSFET switch. The former output amplitude is 500-1000 V; the latter amplitude is 1000-2000 V. Pulse delay time is about 500 ns and can be adjustable between the two trigger pulses. The trigger device can be easily applied to other high-power switches and pulse-power systems by adjusting some electronic components.
