We are using ultrafast shock experiments, carbon condensates recovery and analysis, and large-scale simulations to develop more accurate models of explosives while advancing the emerging field of detonation and high-pressure synthesis science. Predicting the behavior of carbon-rich explosives under strong shock conditions advances the physics, chemistry, and material science of high explosives in support of National Nuclear Security Administration missions.
