Abstract:

The pulsed power Pegasus facility at Los Alamos National Laboratory has been configured to drive cylindrically symmetric shocks into a load region containing multiple density regions. A series of experiments are being performed to permit the development of diagnostic techniques to characterize the spatial distribution and temporal dependence of the cylindrical shocks generated in a 4.5cm diameter X 2cm thick target region. The loads utilized in the preliminary experiments contain multiple regions. Optically transmissive regions are being diagnosed with long pulse, 694nm laser backlighting. Framing cameras and fast optically shuttered cameras are being developed for high resolution image capture. Pulsed x-ray sources permit characterization of material boundary regions through differential x-ray absorption in a radiographic geometry. The desire for multiple visible and x-ray images requires fast time response, electronic imaging techniques.
