A Pulsed Power Source For Plasma Focus Single-shot Experiments

A single shot pulsed power source was developed using two helical flux-compression generators. At an initial 5 kA current injected in the system, a Rogowski coil located in a 4 nH final inductive load recorded a peak current of more than 11 MA. For our application, the pure inductive load will be replaced by a metal foil fuse having the same inductance. The obtained conditions are sufficient to deliver, through a dielectric breakdown switch, a current of more than 2 MA with 4 /spl mu/s risetime on a plasma focus load.
