Low inductance high voltage multi-gap gas switch for high repetition rate pulsed power applications*

The ability to perform high repetition rate pulsed power experiments depends crucially on several factors including fast switching and fast power supply charging times. We present the design from operation of the switch used for a 10Hz fast dense plasma focus experiment to be conducted at the Air Force Research Laboratory at the Wright-Patterson Air Force Base. More importantly, due to the relatively simple design with low cost for parts, modifications such as changes to the internal air pressure or the electrode size can be easily made to increase the versatility of the switch. Furthermore, we will demonstrate how the use of annular electrodes can be a better alternative to the conventional solid disk electrodes by the reduction of inductance from the formation of a cylindrical plasma current carrying sheath and overall switch weight.
