This report describes the fielding of an experiment on the MISER BLUFF Phase II events to quantify the driving parameters behind a shock-driven ground spall phenomenon observed on Phase I events. A detailed background for the experiment is presented in Section II, while the next sections provide details on the deployment of the experiment and the subsequent data acquisition. The report concludes by recognizing that the primary data acquisition instrumentation cameras deployed by the Denver Research Institute did not acquire any information because the events created dust clouds which completely obliterated the test areas. The secondary data, net disc displacement, is reported to be too sparse, and to have too much scatter, to permit the derivation of valid correlations. The report concludes with a recommendation that the measurement be attempted again on the next series of explosive events, or perhaps that a small experiment be mounted to obtain similar information from a laboratory shock tube.
