This LTP aims at setting a laser-driven dynamic compression platform on ID09 in order to perform ps time resolved X-ray diffraction pump probe experiments at high pressure. A 5J laser driver and a point VISAR/PDV diagnostic will be provided to generate the shock compression in materials and characterize their thermodynamic states by velocimetry measurements. With this new high power laser system, pressures in the 100 GPa range could then be generated, an order of magnitude higher than what can be presently achieved on ID09. Over the three years of the LTP, this dynamic compression platform will be mounted, interfaced with the synchrotron beam, tested and made user friendly so that other groups interested by Xray structural studies of matter under dynamical compression could use it. It seems a necessary step to aggregate a community able to make the scientific case for building an XRD station near the High Power Laser Facility (HPLF) of ESRF in the near future.
