Journal ArticleDOI
Absolute X-ray yields from laser-irradiated, Ge-doped aerogel targets
K. B. Fournier,M. T. Tobin,J. F. Poco,K. Bradley,Stephanie Hansen,Christine Anne Coverdale,D. E. Beutler,M. Severson,E. A. Smith,D. L. Reeder +9 more
TL;DR: In this article, the authors measured the production of hv ≥ 10 keV x rays from low-density, Ge-doped aerogel targets at the OMEGA laser (Laboratory for Laser Energetics, University of Rochester).
Journal ArticleDOI
Free-free matrix-elements for two-photon opacity
TL;DR: In this paper, two independent methods to calculate matrix-elements needed for the two-photon opacity and tests the results by the f-sum rule are described. But the results of the AC Stark code are not robust to perturbation.
Journal ArticleDOI
Probing atomic physics at ultrahigh pressure using laser-driven implosions
S. Hu,D. Bishel,David Chin,P. M. Nilson,Valentin V. Karasiev,Igor Golovkin,Min Gu,Stephanie Hansen,Deyan P. Mihaylov,Nathaniel R. Shaffer,Shuai Zhang,T. Walton +11 more
TL;DR: In this paper , the authors report time-integrated and time-resolved x-ray spectroscopy measurements at several billion atmospheres using laser-driven implosions of Cu-doped targets.
Journal ArticleDOI
Homogeneous, Micron-Scale High-Energy-Density Matter Generated by Relativistic Laser-Solid Interactions.
Nicholas Beier,Hunter Allison,P. C. Efthimion,Kirk Flippo,Lu Gao,Stephanie Hansen,K. W. Hill,Reed Hollinger,M. Logantha,Y. Musthafa,R. Nedbailo,V. Senthilkumaran,Ronnie Shepherd,Vyacheslav N. Shlyaptsev,H. Song,S. Wang,Franklin Dollar,Jorge J. Rocca,A. Hussein +18 more
TL;DR: In this paper , the authors present the first demonstration of solid-density, micron-scale keV plasmas uniformly heated by a high-contrast, 400-nm wavelength laser at intensities up to 2×10^{21}
Journal ArticleDOI
Microcalorimeter observations of L-shell spectra of Ne- through Fe-like Au ions in an EBIT
Elmar Träbert,Elmar Träbert,Stephanie Hansen,Gregory V. Brown,Peter Beiersdorfer,Klaus Widmann,Hyun-Kyung Chung +6 more
TL;DR: In this article, the authors measured the L-shell emission from highly charged gold ions in the SuperEBIT electron beam ion trap under bombardment by electrons at energies from 10 to 18 keV.
