Dynamic observations have been carried out with a wide range in time-resolutions from ns to ms to in situ observation of various reactions.
A Time-resolved X-ray Beamline; chemical reactions and more
PF-AR NW14A is an insertion device beamline aiming for time-resolved X-ray diffraction, scattering and absorption experiments. This beamline is particularly suitable for studying ultrafast dynamics in condensed matter systems such as organic and inorganic crystals, biological systems, liquids etc. Structural dynamics triggered by optical laser pulses is captured with the synchronized pump-and-probe system. With the relatively large amount of X-ray photon flux derived from the undulators, it is possible to produce atomic-scale movies of the photo-induced phenomena with 100-ps resolution.
How do metals fracture at nano-scale?
In this study, we in situ examined how the atomic structure of copper changes during the fracture process on the nanosecond scale using X-ray absorption spectroscopy and X-ray diffraction. The fracture was triggered by a shock wave induced by an optical laser and was examined with a single 100-ps synchrotron X-ray pulse with a delay time of 0–200 ns. This novel experimental approach provides insights into how the short- and long-range order of an atomic structure change on the nanosecond scale. The results showed that there was an irreversible change in the deformation state on the nanosecond scale...
