TL;DR: The Z accelerator at Sandia National Laboratories delivers ∼20MA load currents to create high magnetic fields (>1000T) and high pressures (megabar to gigabar) in a z-pinch configuration, the magnetic pressure supersonically implodes a plasma created from a cylindrical wire array, which at stagnation typically generates a plasma with energy densities of about 10MJ∕cm3 and temperatures >1keV at 0.1% of solid density as mentioned in this paper.

TL;DR: This paper presents a meta-modelling study of how nanofiltration affects the response of the immune system to foreign substances, using a model developed by the USGS in the 1990s and refined by the UK.

TL;DR: The Z Refurbishment Project was completed in September 2007 and doubled the stored energy within the existing tank structure and replaced older components with modern, conventional technology and systems that were designed to drive both short-pulse Z-pinch implosions and long-p Pulse dynamic material property experiments.
Journal ArticleDOI
Energy loss to conductors operated at lineal current densities ≤10 MA/cm: Semianalytic model, magnetohydrodynamic simulations, and experiment
William A. Stygar,S. E. Rosenthal,H. C. Ives,T. C. Wagoner,G. O. Allshouse,K. E. Androlewicz,G. L. Donovan,D. L. Fehl,M. H. Frese,T. L. Gilliland,M. F. Johnson,J. A. Mills,David Reisman,P. G. Reynolds,C. S. Speas,R. B. Spielman,Kenneth W. Struve,Arthur Toor,Eduardo Waisman +18 more
TL;DR: In this article, the authors developed a semianalytic expression for the total energy loss to a vacuum transmission-line electrode operated at high lineal current densities, assuming that the current distribution in the electrode can be approximated as one-dimensional and planar.
