TL;DR: In this paper, X-ray-induced explosions in water drops, examined using time-resolved imaging, show interacting high-speed liquid and vapour flows, which may be used for inducing particular dynamical liquid states.
Journal ArticleDOI
Negative Pressures and Spallation in Water Drops Subjected to Nanosecond Shock Waves.

TL;DR: This work generates tension pulses with nanosecond rise times in water by reflecting cylindrical shock waves, produced by X-ray laser pulses, at the internal surface of drops of water, using a nucleation-and-growth model that explains how rapid decompression could outrun heterogeneous cavitation in water, and enable the study of stretched water close to homogeneous Cavitation pressures.

Development of a hard x-ray split-delay system at the Linac Coherent Light Source
Diling Zhu,Yanwen Sun,Donald W. Schafer,Hongliang Shi,Justin H. James,Karl Gumerlock,Ted O. Osier,Randy A. Whitney,Lin Zhang,Josep Nicolas,Brian J. Smith,Andrew H. Barada,Aymeric Robert +12 more
TL;DR: A wavefront-splitting based hard X-ray split-delay system is currently under development at the Linac Coherent Light Source as mentioned in this paper, which uses a series of Si(220) crystal reflections in the horizontal scattering geometry.
Journal ArticleDOI
Pump–probe experimental methodology at the Linac Coherent Light Source
TL;DR: Techniques developed at LCLS to make optical laser pump–X-ray probe experiments both robust and easy to implement at ultrafast X-ray free-electron lasers are presented.
Journal ArticleDOI

TL;DR: In this paper, a controllable train of femtosecond, soft x-ray pulses with the Linac Coherent Light Source (LCLS) free-electron laser (FEL) was demonstrated by enhanced self-amplified spontaneous emission with a 2''m laser and a dechirper device.
