Time-resolved shock physics studies on the Sandia Z accelerator
Abstract
Time-resolved shock wave diagnostics have been a principal tool for understanding the response of materials subjected to intense shock loading. We have extended VISAR interferometry previously developed for high pressure shock physics studies at Sandia to enable a variety of shock wave applications on the Sandia Z Pinch radiation source, including determination of high pressure shock Hugoniots and isentropes, study of drive temperature uniformity in in-direct drive hohlraums, determination of time-resolved ablation pressure histories for validating numerical simulations, and for measurement of radiation flow in secondary hohlraums. This technique has been applied to a number of shock physics experiments on Z, including measurement of shock wave profiles to pressures exceeding 2 Mbar.
