Design of a trigger for the 100 kV Mini-Marx generator

A trigger is designed based on VE4141 thyratron for the 100 kV Mini-Marx generator. The trigger meets the following design specifications: pulse voltage is up to 30 kV, falling time is less than 15 ns, pulse width is more than 500 ns. It can receive optical signal, electric signal and manual signal to trigger. Charge voltage can be adjusted and displayed by the control plane. Pre-trigger and trigger signals are received through an IGBT drive circuit, and are used to control the VE4141 thyratron to discharge and get a high voltage pulsed signal to trigger the 100 kV Mini-Marx generator.
