Show Abstract
A multiwire screw pinch (a variant of a Z pinch) for high-current 100 ns pulsed power generators used for terawatt x-ray radiation is proposed and discussed. Wires, twisted along a curved load surface, are suggested to be an effective way to create the initial axial magnetic field, to begin the rotation of the plasma, and to mitigate the growth of Rayleigh–Taylor instabilities. A screw-pinch design is predicted by a zero-dimensional model to provide more efficient energy transfer from the pulse power generator to the load compared with a straight, cylindrical wire array. © 1999 American Institute of Physics.
