Abstract

We developed a convenient method to mass produce arrays of 1 mm diameter double-layer plastic-bonded explosive (PBX) charges for tabletop studies of shocked insensitive explosives. In the double layer, a pentaerithritol tetranitrate (PETN) booster charge 100 µm long is initiated by a laser-launched flyer plate. The booster sends a shock into a 40 µm long 1,3,5 triamino-2,4,6 trinitrobenzene (TATB) charge. The TATB is initiated more efficiently by the booster charge than by the flyer plate alone. The temperature of the shocked TATB was measured with 2 ns time resolution using optical pyrometry. We could monitor the decomposition of the shocked TATB via the disappearance of its blue-green absorption, and we could monitor the volume explosion by the resulting fast adiabatic cooling.
