We present a set-up for time-resolved X-ray diffraction based on a short
pulse, laser-driven plasma X-ray source. The employed modular design provides
high flexibility to adapt the set-up to the specific requirements (e.g. X-ray
optics, sample environment) of particular applications. The configuration
discussed here has been optimized towards high angular/momentum resolution and
uses Kα​-radiation (4.51 keV) from a Ti wire-target in combination
with a toroidally bent crystal for collection, monochromatization and focusing
of the emitted radiation. 2×105 Ti-Kα1​ photons per pulse
with 10−4 relative bandwidth are delivered to the sample at 10 Hz
repetition rate. This allows for high dynamic range (104) measurements of
transient changes of the rocking curves of materials as for example induced by
laser-triggered strain waves.Comment: 29 pages, 8 figure
