Z-PINCH PLASMA GENERATOR AND PLASMA TARGET

摘要

A configuration of two opposed electrodes with conical depressions and symmetry around an axis along which there is an applied steady magnetic field, is supplied with a pulsed voltage and current to create an azimuthally very uniform pre-ionization cylinder of a working gas as a precursor to stable and accurate compression of the working gas into a Z-pinch plasma photon source or plasma target for laser-pumped photon sources. A further compound hollow electrode configuration permits the generation of a cool, dense, core plasma surrounded and compressed by a hot liner plasma. Modulation of the radial density profile within this core can provide optical guiding for a laser-pumped recombination laser.
