The Naval Research Laboratory "Mag Noh problem", described in this paper, is a self-similar magnetized implosion flow, which contains a fast MHD outward propagating shock of constant velocity. We generalize the classic Noh (1983) problem to include a

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

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

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
