Abstract Text:
Sandia’s Z-Backlighter Facility has been operating the Z-Beamlet laser successfully for several years now, leading to profound progress in the understanding of capsule compression and z-pinch dynamics with the Z-Accelerator pulsed power facility. To enhance temporal resolution and to access plasma regimes of higher density (harder X-rays), Sandia has built the Z-Petawatt laser, which is able to deliver 500J within a 500fs pulse. This presentation will describe the upgraded facility and report on experiments at the 100TW (50/120J with gold/MLD gratings) level that focused on the generation and optimization of energetic X-rays and laser generated protons, which will both be useful as diagnostic tools or drivers in Sandia’s High Energy Density Physics mission.
