Journal ArticleDOI
Observations of plasmons in warm dense matter.
Siegfried Glenzer,O. L. Landen,Paul Neumayer,Richard W. Lee,Klaus Widmann,S. W. Pollaine,R. J. Wallace,Gianluca Gregori,A. Höll,T. Bornath,R. Thiele,V. Schwarz,Wolf-Dietrich Kraeft,Ronald Redmer +13 more
TL;DR: The forward scattering spectra of a laser-produced narrow-band x-ray line from isochorically heated beryllium show that the plasmon frequency is a sensitive measure of the electron density.
Observations of Plasmons in Warm Dense Matter
S. H. Glenzer,O. L. Landen,Paul Neumayer,Richard W. Lee,Klaus Widmann,S. W. Pollaine,R. J. Wallace,Gianluca Gregori,A. Höll,T. Bornath,R. Thiele,Schwarz,Wolf-Dietrich Kraeft,Ronald Redmer +13 more
TL;DR: In this article, the collective x-ray scattering measurements of plasmons in solid-density plasmas were presented, showing that the plasmon frequency is a sensitive measure of the electron density.
Journal ArticleDOI

Hastings,Siegfried Glenzer +29 more
TL;DR: In this article, an X-ray laser was used to observe the transition from plasmas and condensed matter to warm dense matter (WDM) in planetary interiors, and the transition to WDM was observed by using a WDM detector.
Journal ArticleDOI
Nanosecond formation of diamond and lonsdaleite by shock compression of graphite
Dominik Kraus,Alessandra Ravasio,Maxence Gauthier,Dirk O. Gericke,Jan Vorberger,Jan Vorberger,S. Frydrych,J. Helfrich,Luke Fletcher,Gabriel Schaumann,Bob Nagler,B. Barbrel,Benjamin Bachmann,E. J. Gamboa,Sebastian Göde,Eduardo Granados,Gianluca Gregori,Hae Ja Lee,Paul Neumayer,William Schumaker,Tilo Döppner,Roger Falcone,Siegfried Glenzer,Markus Roth +23 more
TL;DR: This experiment provides new insights into the processes of the shock-induced transition from graphite to diamond and uniquely resolves the dynamics that explain the main natural occurrence of the lonsdaleite crystal structure being close to meteor impact sites.
Journal ArticleDOI

TL;DR: The Petawatt High Energy Laser for heavy Ion eXperiments (PHELIX) as discussed by the authors has been commissioned for operation in stand-alone mode and, in combination with ions accelerated up to an energy of 13 MeV/u by the heavy ion accelerator UNILAC enables a large variety of unique experiments.
