Abstract

Abstract

By bi-sensitivity VISAR, the shock initiation of JB9014 under divergent spherical shock wave (20 GPa) was experimentally studied. The particle velocity profiles of explosive/window interfaces at different positions were measured. The results show that the run to detonation is within 2~3 mm, and steady detonation is fully developed at 3~5 mm. Preliminary modeling was carried out with hydrocode. The simulation is in accordance with the experimental results.
