Tungsten wire-array Z-pinch experiments at 200 TW and 2 MJ
R. B. Spielman,C. Deeney,Gordon A. Chandler,Melissa Douglas,D. L. Fehl,Maurice Keith Matzen,Dillon H. McDaniel,Thomas J. Nash,John L. Porter,T. W. L. Sanford,J. F. Seamen,William A. Stygar,Kenneth W. Struve,S. P. Breeze,J. S. McGurn,Jose A. Torres,D. M. Zagar,T. L. Gilliland,D. O. Jobe,John Lee McKenney,R. C. Mock,M. Vargas,T. C. Wagoner,D.L. Peterson +23 more
TL;DR: In this article, the authors used a 60 TW/5 MJ electrical accelerator located at Sandia National Laboratories to implode tungsten wire-array Z pinches, which achieved an x-ray power of ∼200 TW and an xray energy of nearly 2 MJ.
Journal ArticleDOI

Matthew R. Gomez,Stephen A. Slutz,Adam B Sefkow,Daniel Sinars,Kelly Hahn,Stephanie Hansen,Eric Harding,Patrick Knapp,Paul Schmit,Christopher Jennings,Thomas James Awe,M. Geissel,Dean C. Rovang,Gordon A. Chandler,Gary Wayne Cooper,Michael Edward Cuneo,A. J. Harvey-Thompson,Mark Herrmann,M. H. Hess,O. Johns,Derek C. Lamppa,Matthew Martin,Ryan D. McBride,Kyle Peterson,John L. Porter,G. K. Robertson,Gregory Rochau,Carlos L. Ruiz,Mark E. Savage,Ian C. Smith,William A. Stygar,Roger Alan Vesey +31 more
TL;DR: This Letter presents results from the first fully integrated experiments testing the magnetized liner inertial fusion concept, indicating significant fuel magnetization given that the estimated radial areal density of the plasma is only 2 mg = cm(2).
Journal ArticleDOI
Pulsed-power-driven high energy density physics and inertial confinement fusion research
M. Keith Matzen,M. A. Sweeney,R. G. Adams,James R. Asay,James E. Bailey,Guy R. Bennett,David E. Bliss,D.D. Bloomquist,Thomas A. Brunner,R. B. Campbell,Gordon A. Chandler,Christine Anne Coverdale,M.

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.
Journal ArticleDOI
Architecture of petawatt-class z-pinch accelerators.
William A. Stygar,M. E. Cuneo,Daniel Headley,H. C. Ives,R. J. Leeper,Michael G. Mazarakis,Craig L. Olson,John L. Porter,T. C. Wagoner,Joseph Ray Woodworth +9 more
TL;DR: In this article, an accelerator architecture that can serve as the basis of the design of petawatt-class $z$-pinch drivers is presented. But it does not include intermediate store transmission lines, multimegavolt gas switches, or a laser trigger system.
Journal ArticleDOI

M. E. Cuneo,Eduardo Waisman,Sergey Lebedev,J. P. Chittenden,William A. Stygar,Gordon A. Chandler,Roger Alan Vesey,Edmund Yu,Thomas J. Nash,David E. Bliss,G. S. Sarkisov,T. C. Wagoner,G. R.

TL;DR: Cuneo et al. as discussed by the authors showed that very late acceleration is not a universal aspect of wire array implosions and varied the ablation period between 46% +/-2% and 71%+/-3% of the stagnation time.
