FY18 J23X PSDT Final Report: Shock Initiation of PBX 9502 Lot HOL88H891-008
This report details a series of plate impact experiments on the insensitive explosive PBX 9502 (95% TATB, 5% Kel-F 800) with lot number HOL88H891-008. This is a ’virgin’ lot (no recycled material used), for which many detonation performance measurements are available; the addition of these 1-D shock initiation experiments will aid model calibration efforts for this material. Samples were machined from isostatically-pressed billets with anominal density of 1.89 g/cc. The evolution of the shock to a detonation was characterized by 9 embedded magnetic particle velocity gauges, and 116 embedded magnetic time of arrival gauges (AKA shock trackers). Pho-ton Doppler velocimetry (PDV) with a LiF window was used at the back surface of the samples to capture the wave profile exiting the sample. Six experiments were performed, covering a pressure range of 10.8–18.6 GPa and run distances to detonation of 2.7–12.2+ mm. The shock initiation of this lot is found to be consistent with Pop plots reported for other lots of PBX 9502. All data have been uploaded to the LANL Small Scale Database for use by the research community.
