Ultrahigh magnetic field dynamic transformers [for pulsed power]

The principles involved in generating high voltage pulses in a helical coil centrally positioned on the axis of a cylindrically imploding ultrahigh magnetic flux compression were first reported in the early 1970s. More recently, plate generators coupled to high-voltage transformers have been used to generate voltages up to 1 MV. In both cases, however, it was necessary for the winding in which the voltage was generated to be heavily insulated. This paper describes a different approach, and calculates the output expected for the case in which a dynamic transformer is used with either existing ultrahigh magnetic field cascade systems, or other converging systems, or a /spl theta/-electromagnetic megajoule flux compression device. A few potential applications are outlined. The paper is presented to advance a proposal to the International DIRAC team (USA, Russia, Australia and Japan) and also to any laboratory having the necessary facilities, such as the Megagauss Laboratory, ISSP, Tokyo, Japan.
