Hybrid X pinches

POSTER

Abstract

A hybrid X-pinch configuration consisting of solid conical electrodes connected by a wire has been tested on four different generators with currents varying from 270 kA to 1 MA and risetimes ranging from 50 ns to 170 ns. Wires of different materials were loaded through holes in the cones; wire lengths were varied from 0.6 to 2 mm. It was possible to optimize the wire material, length and diameter so that most of these hybrid X pinches generated an intense single burst of soft x-rays with energy yield comparable with the one in standard X pinches. In such cases, the single hot spot that was of micron-scale size. Hybrid X pinches generate less hard x-ray intensity than standard X pinches. Early stage of the wire explosion in the hybrid X pinches was studied.
