1.2 MV, 800 kA, 150 ns pulsed power generator for powering Field Reversed Ion Ring Experiments

The Field-Reversed Ion Ring Experiment (FIREX) program at Cornell University is designed to reach the goal of producing a field-reversed configuration (FRC) with current carried by an ion ring trapped in a magnetic mirror. Production of an ion-ring FRC is expected to have favorable stability and confinement characteristics for magnetically-confined fusion. Past experimental results, theoretical analysis and ion ring injection simulations were used to determine the electrical requirements of the generator. Following a brief description of the FIREX program, the electrical and mechanical design of a 1.2 MV, 800 kA, 150 ns pulsed power source for driving an Exploding Metal Foil active Anode Plasma Source (EMFAPS) type ion diode is described. SPICE circuit analysis results are also presented.
