title = "Tracking temperatures and growth of hot spots in a simplified plastic-bonded explosive under shock compression",
abstract = "The ability to probe the time-dependent hot spot formation processes in explosives under shock compression is critical to understanding the initiation of explosives used in munitions and nuclear weapons. We have developed a tabletop apparatus that allows us to impart shocks on a sample to study the relationship between hot spot formation and shock initiation. By using laser-driven impactors, we impart shocks lasting several ns and compress sample targets up to 10s of GPa. Using multi-frame fast photography with ns temporal resolution we visually track thermal emission and its evolution over time. Additionally, we measure the time dependent temperatures using a multichannel optical pyrometer coupled to a microscope objective that can resolve features down to a few microns. The sample targets in this study consist of miniature arrays of explosive crystals embedded in various polymers. To date we have produced time-resolved images and simultaneous temperature measurements of shock-induced hot spots in a model plastic-bonded explosive.",
