Laser-driven x-ray diffraction in the terapascal regime

X-ray diffraction has been used extensively over the past century to interrogate material properties such as crystal structure, grain size, texture, defects, and strength. The recent implementation of an x-ray diffraction platform at large laser facilities such as Omega and the NIF will enable these studies for materials at extreme pressures in excess of 1 TPa (10 Mbar). In addition, the short exposure x-ray times will allow us to investigate the time-dependence of these phenomena on the dynamically-compressed samples.
