Compact Marx generator for repetitive applications

We designed a compact repetitive Marx generator. The Marx generator contains 25 stages consisted with capacitor banks and spark gap switches. We used door knob ceramic capacitors. The capacitors are charged through inductors by a capacitor charging power supply. The length and the diameter of the Marx generator are about 150 cm and 60 cm, respectively. We conducted a preliminary test at the condition of low charging voltage using nitrogen gas. We present the characteristic of the Marx generator and discuss the design issues such as high voltage insulation.
