Compact High Repetition & High Voltage Marx Generator

A general purpose compact Marx generator was built and tested.
The Marx generator has 25 stages.
The designed maximum output voltage of the Marx generator is 1 MV at open circuit condition.
The overall size of the Marx generator is 150 cm in length and 60 cm in diameter.
The Marx generator has pulse width over 40 ns and low jitter
performance at burst mode operation with impedance around 99 Ω.
We expect that the Marx generator can be used in several high voltage pulse applications.
