Numerical simulations of pulsed power driven Z-pinch plasma loads are providing the stimulus and guidance for the development of the superclass pulsed power driven x-ray simulators. Design concepts are being explored for the development of generators with power levels in the 10--100 terawatt range to drive Z-pinch material loads to high temperature and density plasmas for the production of 100`s of kilojoules to 10`s of Megajoules of soft x-rays. They will investigate the radiative properties of a krypton gas puff load for a generic high current multiterawatt generator. For a prescribed set of electrical characteristics they will investigate the radiative performance of the load driven by and self-consistently coupled to a circuit. There is no intent to optimize either the power flow/load coupling or the radiation from the load. The generator will be represented by a driver capable of producing short circuit currents of 60, 80, and 100 mega-amps to a load over 100 ns current risetime. The purpose of this investigation is to determine the influence of the L- and K-shell dynamics on the K-shell yield for krypton loads consisting of annular shells or uniform fills of 3 and 5 cm radius and 3 cm length, respectively.
