TL;DR: In this article, the authors dealt with TTF/FLASH in the XFEL context, general layout of the X-FEL facility, the X FEL accelerator, undulators for SAES and spontaneous emission, infrastructure and auxiliary systems, commissioning and operation, project management and organization, cost and time schedule.

TL;DR: The XCCA concept opens up a fascinating view into the world of disorder and will definitely allow, with the advent of free electron X-ray lasers, an accurate and systematic experimental characterization of the structure of the liquid and glass states.

TL;DR: This work uses femtosecond X-ray pulses from a free-electron laser to study thin film samples with magnetic domain patterns and observes an infrared-pump-induced change of the spin structure within the domain walls on the sub-picosecond timescale, demonstrating the importance of spin-dependent electron transport between differently magnetized regions as an ultrafast demagnetization channel.

TL;DR: The results of a high-resolution neutron diffraction experiment with a fully deuterated methane hydrate type I at temperatures of 2, 100, and 150 K were obtained in this article.

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.
