Direct Measurements of Shock-Wave Propagation in CH Using Streaked X-Ray Radiography and VISAR

ORAL

Abstract

Measurements of shock-wave propagation in CH were carried out with one-dimensional streaked x-ray radiography and a line-imaging velocity interferometer. The shock was driven with a 2.5-ns laser pulse at focused intensities of up to $4 \times 10^{14}$ W/cm$^2$. The shock-velocity measurements show good agreement with each other to within experimental error. This combination of techniques is being investigated for future applications in absolute equation-of-state studies. This material is based upon work supported by the Department of Energy National Nuclear Security Administration under Award Number DE-NA0001944 and the Stewardship Science Graduate Fellowship Grant Number DE-NA0002135.
