TL;DR: The experimental creation of a solid-density plasma at temperatures in excess of 106 kelvin on inertial-confinement timescales using an X-ray free-electron laser is reported and insights are obtained into the evolution of the charge state distribution of the system, the electron density and temperature, and the timescale of collisional processes.
Journal ArticleDOI

TL;DR: The results suggest that a magnetic material's microstructure can be engineered to control transient laser-excited spins, potentially allowing faster (~ 1 ps) spin reversal than in present technologies.
Journal ArticleDOI
Photon Beam Transport and Scientific Instruments at the European XFEL
Thomas Tschentscher,Christian Bressler,Jan Grünert,Anders Madsen,Adrian P. Mancuso,Michael T. Meyer,Andreas Scherz,Harald Sinn,Ulf Zastrau +8 more
TL;DR: The European XFEL as discussed by the authors is a free-electron laser (FEL) user facility providing soft and hard X-ray FEL radiation to initially six scientific instruments.
Journal ArticleDOI

TL;DR: The results are found to disagree with the predictions of the extensively used Stewart-Pyatt model, but are consistent with the earlier model of Ecker and Kröll, which predicts significantly greater depression of the ionization potential.
Journal ArticleDOI

TL;DR: The first single-shot images of ferromagnetic, nanoscale spin order taken with femtosecond x-ray pulses are presented, opening new ways to combine ultrafast laser spectroscopy with sequential snapshot imaging on a single sample, generating a movie of excited state dynamics.
