Characterization and comparison of X-ray focusing optics for ultrafast X-ray diffraction experiments

Applied Physics B, 2008
We have characterized and compared the performance of different types of multi-layer optics for the focusing of femtosecond X-ray pulses. Using X-ray pulses at 8 keV, from a laser-driven plasma source we have measured the spatial distribution of the diffracted X-rays directly after and in the focal plane of the various X-ray optical devices.

Ultrafast X-ray diffraction and absorption

1997
Abstract The conventional way to study ultrafast chemical dynamics is by ultrafast optical pump/probe experiments. Unfortunately, such optical measurements cannot be directly inverted to give the desired positions of the atoms as a function of time except in very favourable cases where the system is small and there is a prior ...

Subpicosecond X-ray diffraction mesasurement of InSb ultrafast melting

Ultrafast Phenomena, 2000
Subpicosecond atomic behaviour following 100 fs laser excitation is investigated in InSb by time-resolved X-ray diffraction. The process of non-thermal melting is observed and characterized in the subpicosecond time-scale.

An Ultrafast X-Ray Diffraction Apparatus for the Study of Shock Waves

AIP Conference Proceedings, 2004
The use of X‐ray diffraction for the study of shock physics has been pursued for decades. Conceptually, changes in the diffraction line, including broadening and shifts, provide details about the nature of compression, plasticity, phase, and kinetics of the phase transition for the material being shock‐loaded.

Theory of ultrafast time-resolved X-ray and electron diffraction

1997
Abstract The interaction between a monoenergetic X-ray beam and the electronic distribution of a crystalline sample results in the formation of a well-defined X-ray scattering pattern. The scattering pattern is highly sensitive to crystal structure and the inherent microscopic order of nuclei within the crystal in terms of both ...
