Abstract

In an effort to understand the influence of different surface finishes and the effect of ejecta mass on free surface temperature measurements, we performed a series of high-explosively (HE) shocked tin experiments. In this series of experiments the surface finish (i.e, specular, shallow grooves (16 μinch), deep grooves (200 μinch) and "ball-rolled" surfaces) and the ambient atmosphere (from 1.2 torr, to atmospheric air, as well as 1 atm helium) were varied. With a ~180 kbar shock pressure the temperature results agreed for all but the very deep groove (>200 μinch) surfaces investigated.
