A series of pulsed power driven recent Kr gas-puff experiments on the Sandia National Laboratories Z machine have produced intense X-rays in the multi-keV photon energy range. Krypton spectra from Z pinch implosions can be used to analyze the presence and dynamics of the emitting regions, which could dominate the Kr K- and L-shell yields. This theoretical investigation of highly charged high atomic...
Substantial progress has been made in developing plasma radiation sources from Z-pinch implosions. University pulsed power machines provide a cost effective platform to study alternative mechanisms of producing x-rays in exploratory experiments that may provide guidance in search of further improvements on the larger machines. Radiation from puff-on-wire implosions were studied by Chuvatin et al....
Advances in diagnostics at the refurbished Z facility at Sandia National Laboratories (SNL) now allow spatially and temporally resolved spectra to be obtained, with improved signal-to-noise ratios. Z-pinch simulation models have also improved, due both to substantial advances in the understanding of the underlying physics, and to the development of more detailed and accurate atomic databases. We will...
Summary form only given. K-shell X-rays have been studied with various materials at the 20-MA (pre-refurbished) Z accelerator. This paper presents results obtained for the ablation dynamics and stagnation physics of single and nested copper z-pinches with varying initial load diameters. Monochromatic imaging and shadowgraphy provide detailed information regarding the ablation of the wires and the...
