Abstract

The mechanism of initiation of detonation in low-density PETN by laser ablation of Titanium (Ti) driven into the PETN and subsequent evolution of the detonation wave in a direct optical initiation (DOI) detonator were studied both experimentally and with a model simulation. The DOI detonator is the optical analogue of the exploding bridgewire (EBW)detonator. We have sought to understand, both experimentally and theoretically, several important stages in the timeline of the DOI detonator operation. A discussion of the Ti-laser ablation stage of the detonator is presented. Experiments and simulation that determine the distance to detonation are presented. Finally, ongoing efforts to combine all the studies into an integrated model of the entire DOI detonator timeline will be discussed.
