Title: Review of PBX 9502 Pop Plot data

Abstract

Pop plot data (distance of run and time to detonation as a function of shock pressure) is a simple characterization of shock initiation of a high explosive. It is used, along with other data, to calibrate reactive burn models. For the insensitive TATB based explosive PBX 9502, there are data at 5 initial temperatures (77 K, -55 C, 23 C, 76 C, 130 C) and for several lots. Here we review the dependence of the Pop plot on temperature and the variation with lot. There is a significant increase in shock sensitivity with temperature.Since the Pop plot is important for modeling, fit parameters are interpolated to cover the temperature range –55 < T < 76 C. The scatter in the data and variation with lot is important for assessing the accuracy to which a model can be calibrated.
