Inductive pulse forming techniques appropriate for the driving of imploding plasmas have been explored with special attention given to a suitable opening switch. Parametric investigations of circuit models indicate that imploding load performance is relatively independent of opening switch parameters. Extrapolation of existing experimental and computer simulated data leads to conceptual design criteria for a fused metal foil opening switch which will be implemented on a 1.9 MJ system. The inductive system compares favorably with the direct capacitor driven system in terms of kinetic energy with the definite advantage of shorter time scales on which the energy is delivered to the implosion.
