High-speed X-ray transmission tomography for detonation investigation

This article describes the procedure and results of high-speed X-ray tomography application to reconstruct density distribution of detonation products of condensed explosives from the results of measurements with synchrotron radiation. Data obtained for a cylindrical charge (12.5 mm in diameter) of pressed TNT of density of 1.6 g/cm3 are compared with the results of solution of the corresponding gas-dynamic problem of stationary detonation. Qualitative and satisfactory quantitative compliance of the experimental and calculated results is established. Particularities of the procedure and the distribution obtained are analyzed. It is noted that the procedure on the whole and the results can be used to define the known equations of state of detonation products more accurately and to construct new ones.
