Optical Detonator on the Basis of PETN Dopped with Cobalt Nanoparticles

Abstract

The optical detonator's cup, performing selective sensitivity to laser radiation, was suggested. The cup is based on the secondary explosive PETN, which contains cobalt nanoparticles. The optimal nanoparticles' size was estimated using hot-spot model of laser initiation. The critical energy density for the suggested explosive composition for the cup was determined experimentally.Keywords: PETN, cobalt nanoparticles, optical detonator, laser initiation.
