Characteristics of JOB-9003 in Double Shocks Experiments

One-dimensional plate impact experiments were performed to study the double shocks to detonation transition and Hugoniot state in the HMX-based explosive JOB-9003.The flyer was a combination of sapphire and Kel-F, which could pass two different pressure waves after the impact.We measured the particle velocities at the interface and the different depths using the Al-based electromagnetic particle velocity gauge technique, and obtained the particle velocity-time diagram, according to which we calculated the impact velocity, the shock wave velocity, and then the Hugoniot relation of the explosive.By comparing them with the existing experiment data in the Pop plot, we can draw the conclusion that the explosives pressed by the double shocks will exhibit desensitization features.
