Marx generator using pseudospark switches

The design and preliminary operation of the major subsystems of a Marx style pulse generator using advanced pseudospark devices are presented. The bank consists of three 150 nF / 40 kV capacitors connected with three floating FS2000 type pseudospark switches. These switches can hold off 35 kV and pass up to 10 kA at repetition rates approaching 1 kHz. The expected lifetime of >200 kC and the relatively low housekeeping power of <50 W make the pseudospark switch an excellent candidate in compact Marx generator applications. Preliminary operation of the floating housekeeping units essential to the Marx generator is presented in detail.
