Time resolved x-ray radiographic measurements at high photon energy ([similar to]7 keV) are used to observe radiation-driven shock propagation and interface motion in solid density plastic samples, produced by indirect drive on the Nova laser. Measurements of x-ray transmission through the shock compressed material are used to infer a density of approximately three times solid. In addition, by doping a section of a sample with high-[ital Z] material (Br) for radiographic contrast, the shocked particle velocity was measured by observing the motion of the interface between the doped and nondoped materials resulting from acceleration by a shock.
