Figure 1

Experimental configuration arranged in a transmission geometry at the DCS laser station showing the pink (non-monochromatic) beam profile of the U17 undulator x-ray source, together with XRD diffraction ring from the Sm sample and processed point-VISAR data collected at the Sm/LiF interface (time zero corresponds drive laser impact). Bright spots correspond to reflection from LiF single crystal. The target assembly consists of kapton ablator backed by Sm foil, which is backed by a LiF window.
