ISENTROPIC COMPRESSION DATA ON LX-04 EXPLOSIVE AT 150?C USING THE Z ACCELERATOR

By D E Hare, K S Vandersall, F Garcia, J Davis, C Hall and J W Forbes

Abstract

Isentropic compression data was collected on LX-04 explosive (85% HMX and 15% Viton by weight) at 150 C using the Sandia National Laboratories Z accelerator facility. A ramp compression wave was applied to the explosive samples mounted on aluminum panels with VISAR interferometry measuring the sample and backing window interface velocity. Heating was obtained by wrapping band heaters around a thermal mass attached to each panel and temperatures were recorded by thermocouples at several locations on the panel. This work will outline the methods used, discuss the VISAR interface velocities, and present the preliminary data obtained on heated LX-04. These results demonstrate the ability to perform experiments on preheated samples to obtain isentrope data
