Proceedings ArticleDOI
The effect of adding a center jet to Argon gas puff implosions at the Z facility
A. J. Harvey-Thompson,Brent Manley Jones,Christopher Jennings,D. J. Ampleford,Derek C. Lamppa,Stephanie Hansen,Christine Anne Coverdale,M. R. Gomez,Gregory Rochau,Duane D. Johnson,M. C. Jones,Nathan W. Moore,Timothy McGuire Flanagan,J. Reneker,Marc Ronald Lee Jobe,Larry Martin Lucero,M. E. Cuneo,J.W. Thornhill,John Giuliani,Arati Dasgupta +19 more
TL;DR: Argon gas puff implosions have been found to be an extremely efficient source of K-shell x-rays (3-4 keV) on the Z pulsed power facility at Sandia National Labs as mentioned in this paper.
Proceedings ArticleDOI
Diagnostic constraints on the amount of cold mass in imploded argon pinches on Z
J. P. Apruzese,Brent Manley Jones,John Giuliani,N. D. Ouart,J. W. Thornhill,A. J. Harvey-Thompson,D. J. Ampleford,Christopher Jennings,Stephanie Hansen,N. W. Moore,Derek C. Lamppa,Christine Anne Coverdale,M. E. Cuneo,Gregory Rochau +13 more
TL;DR: The refurbished Z machine at Sandia National Laboratories has been successfully configured to drive gas-puff Z pinches as discussed by the authors, and a series of experiments using Ar loads produced K-shell yields of 330 ± 9% kJ, with highly reproducible Kshell spectra and power pulses.
Journal ArticleDOI
Self-consistent and detailed opacities from a non-equilibrium average-atom model
TL;DR: In this article , a simple modification to the bound-state occupation factor of a DFT-based average-atom model was proposed to capture essential non-LTE effects in plasmas, including autoionization and dielectronic recombination.
Proceedings ArticleDOI
Effect of wire material on wire array implosions
D. J. Ampleford,Brent Manley Jones,M. C. Jones,Christopher Jennings,Stephanie Hansen,M. E. Cuneo,Christine Anne Coverdale,Mark E. Savage,William A. Stygar,M. R. Lopez,John P. Apruzese,J.W. Thornhill,Y. K. Chong,John Giuliani +13 more
TL;DR: In this paper, a series of experiments where the wire material is varied (Al, Stainless Steel, Cu, W), however the array setup is fixed at 65mm diameter and 2.5mg mass.
