Abstract :
A special instrumentation was developed for the investigation of explosions by synchrotron radiation with 250ns time resolution. It consists of an explosion chamber, detonation front sensors (wire detectors) and X-ray detectors. The time dependence of the absorption coefficient of the explosive material was measured during the explosion. In the same experiments, the SAXS and the diffraction signal were observed. In the first experiments, hexogen-TNT alloy was used to obtain diamond powder as explosion product. In this experiment the SAXS intensity increased sharply for 1500ns. This is an unusual result, because according to theory, most chemical transformations finish in about 200ns. The test experiment has shown that it is possible to receive a time resolution of 20ns.
