A zero dimensional thin-shell implosion model with a coupled equivalent circuit for the description of an imploding nested wire array or gas puff is presented. Model results have been compared with data from imploding stainless-steel wire arrays and

Till recently, measurements of the magnetic field in gas-puff z-pinch implosions were limited to low density and temperatures typically found at very early times and outside the pinch radius ( r≥ 9 mm and t≤ −90 ns). However, recent, more accur

New measurements of the magnetic field at several axial position along the column of an imploding plasma column, as a function of radius and time are presented. The optical configuration, efficient in UV-visible light collection, provided simultaneou

The use of the recombination continuum for x-ray radiation production in Z pinches has been discussed as an option 1 for generating high yields in the warm photon energy range, ħω > 13 keV. The free-bound continuum emission is an inherently weaker

Implosions of wire array and gas puff loads on pulsed power facilities, such as the Z machine at Sandia National Laboratories, have been successful in producing 1-10 keV soft x-ray sources. Titanium wire array loads imploded on Z have produced ~100 k

An intriguing result is that a small fraction of Xe (0.8% by number in the center jet) can have a significant impact on the emitted K-shell radiation in an Ar gas-puff implosion. This result was recently obtained from a pair of experiments on Sandia

We present here the detailed measurements of radial distribution of the magnetic field in a gas-puff z-pinch plasma at the final stages of the implosion phase and at stagnation. While the measurements are chordal, the radial distribution of different

Three argon gas-puff implosions were performed on the Z-machine at Sandia National Laboratories. These three loads had the same density profile from an 8 cm diameter nozzle, a 1 mg/cm mass, and had a 2.5 cm length. The experiments produced similar K-
