Development of an Ultrafast X-ray Source for Measurements of Shocked Material Structural Dynamics
Abstract
An experiment to study the structural dynamics at the ultra-fast time scale in shocked metal samples is presented. The technique development of an ultrafast x-ray diffractometer to generate "molecular movies" is described. Preliminary results of static x-ray measurements are presented. Initial experiments use 150 mJ of a 100fs Ti:Sapphire laser to excite K-alpha x-ray emission in an aluminum wire. The x-ray emission is relayed using a spherical Quartz crystal to the sample target. Measurements of the source spectrum and imaging at the sample plane are presented as well as static diffraction patterns from an unshocked Quartz sample recorded on x-ray CCD. Plans for experiments using Cu K-alpha emission will also be described.
