Shock Release Experiments (SRE) platform development for JASPER

ORAL

Abstract

The Shock Release Experiments (SRE) platform on the Joint Actinide Shock Physics Experimental Research (JASPER) facility has been developed to investigate the off-Hugoniot release path of metals that are shocked to high pressure using plate impact. This simple and direct measurement provides a release isentrope of a shocked sample in a single experiment. The release path is determined by measuring the free surface velocity of six witness materials of lower impedance. We present the details of the shock release platform, and an example of the release behavior of tantalum.
