Abstract Text:
Driving a shock in argon gas with velocity in excess of 100 km/s creates a system where the density and temperature structure of the shock are altered by the radiation transport from the shock-heated matter. Experiments at the Omega Laser employed several diagnostic configurations to characterize this system, including incoherent Thomson scattering spectrometry, x-ray radiography, and a novel method of imaging the x-rays scattered from material in the high-density cooling layer. The resolution of radiographic images
produced from area backlighting with chlorine Heα and Lyα is measured µm and initial imaging Thomson scattering results are shown. Plans for future iterations of radiative shock experiments are also discussed.
This research was sponsored by the NNSA Stewardship Sciences Academic Alliances and the National Laser User Facility through DOE Research Grants DE-FG52-07NA28058 and DE-FG52-04NA00064, and by other grants and contracts.
