In this work we carried out our experiments on measuring small angle x-ray scattering (SAXS) during trinitrotoluene detonation. Registration of SAXS signal at detonation of high explosives (HE) allows to measure fluctuation of density, which are connected with process of carbon condensation. Here we present dynamics of particles sizes during detonation of cast trinitrotoluene charge in diameter of 40 mm.

We also carried out SAXS calculation with real spectrum (which consist of the viggler radiation, TNT absorption and the DIMEX-3 detector absorption). Our calculation shown that average sizes of nanodiamonds behind the detonation front could be restored from measured data on pink SR beam SAXS distribution.

Our experiments with using synchrotron radiation were made on SYRAFEEMA (Synchrotron Radiation Facility for Exploring Energetic Materials) station at the accelerating complex VEPP-4M (Budker Institute of Nuclear Physics). This new station allowed to increase the mass of the studied charges up to 200 grams in comparison with similar station “Extreme states of matter” at the accelerating complex VEPP-3.
