Abstract

Research on a new type of wire-array z pinch based on a slow generator was conducted. When a current was applied to divergently aligned two Cu wires of 25 µm in diameter, the wires were interrupted near the inner electrode and contracted locally. A soft x-ray pulse was generated, and a spatially isolated hot spot was observed near the inner electrode. A new method for converging a wire array to a single point was presented.

Keywords

divergent z pinch, wire array, hot spot, soft x-ray radiation, implosion
