Abstract
Summary forn only given. We review the experimental design and results from recent radiative shock experiments at the Omega Laser facility. Using a beryllium pusher to drive a shock in excess of 100 km/s in a xenon-filled shock tube creates a system where the density and temperature structure are significantly affected by radiation transport from the shock-heated matter. To measure this system with high accuracy, streaked x-ray radiography and x-ray Thomson scattering diagnostics were employed on each shot. We detail how this diagnostic combination allows for precise interrogation of the different regions of the shock, including the radiation-heated upstream precursor, the radiatively collapsed cooling layer, and the downstream material. Spatially and temporally correlated data from the x-ray streak camera and gated spectrometer is shown, and plans for future iterations of radiative shock experiments are also discussed.
