The Detonation Shock Dynamics (DSD) calibration for the plastic-bonded ex- plosive PBX 9501 is revisited, incorporating recent slab geometry tests conducted by Jack- son and Short. To address the question of which geometry (slab or rate-stick) may be preferable for calibration, we will present a series of PBX 9501 DSD calibrations obtained using only detonation phase velocity and front shape measurements extracted from the slab geometry tests for a number of Dn(κ) functional forms. The corresponding predictions of the diameter effect curves are then compared to the available data. Calculations of the thickness effect curve and slab front shapes from a previously obtained PBX 9501 DSD calibration by Aslam2 (based on cylindrical rate-stick experiments with two front shapes obtained for a single charge-diameter) are, in turn, compared to the new slab geometry test data. The compatibility of the two data sets for DSD calibration of PBX 9501 is evaluated and discussed.
