Inertial fusion research based on pulsed power
PBFA II, with design parameters of 3.5 MJ and 100 TW, is being designed to allow inertial fusion ignition experiments using imploding foils or light ion beams. Flexibility is being retained to implode a cylindrical foil through magnetically insulated power concentration at 30 MA or to drive one or more ion diodes operating in the 10-MV range. In both cases our goal is to deliver 100 TW/cm/sup 2/ and 1 MJ to a target in order to investigate ignition and possibly breakeven. Imploding foil data on Proto II has demonstrated that electromagnetic energy can be efficiently converted into foil kinetic energy with the output increasing as the square of the foil current. Our experiments have reached 60 kJ at 5 MA with the foil imploding in 80 ns and stagnating in 10 ns. This implosion demonstrates adequate stability, and modeling has shown that this behavior should extrapolate to higher currents if the implosion time is less than 100 ns. In order to extend the scaling data to 8 MA, we have modified Proto II by extending magnetic insulation to inhibit insulator flashover.
