A Compact Fast Marx Generator with Repetition Rate 10Hz

Abstract

A compact fast Marx generator has been designed, built and tested. The generator is made of 10 inductively isolated capacitor stages. All the capacitors and switches are placed in a stainless steel about 400 mm diameter and 500 mm high. The cylinder is filled with SF6 and N2 gas so as to enhance the insulation ability. The output voltage of the generator achieve to 300 kV with a repetition 10Hz. The risetime of the pulse is about 15 nanoseconds with a water resistance about 50 Ohm.
