Abstract

Section titled ā€œAbstractā€

This work presents the results of experiments using synchrotron radiation from the VEPP-4M accelerator complex at Budker Institute of Nuclear Physics. Dynamic of small-angle X-ray scattering of synchrotron radiation was implemented on the synchrotron radiation beamline 8-b. Here given beam parameters and described elements of the station and detector system. The distance from the axis of the explosive charge to the detector was 3432 mm. The strip size of the detector DIMEX was 0.1 mm. Thus, a single channel of the detector DIMEX in these experiments corresponded to the scattering angle 2Īø: 1 detector channel = 0.02914 mrad. The SAXS measurement technique on this station enables detection of nanoparticles ranging in size from 2 nm to 200 nm with exposure time 73 ps for one frame. It is possible to record 100 frames with interval 100 ns. In this work used TNT with 30 mm in diameter and 55 mm in length. Ultra fine diamonds of 2 nm size was detected behind the detonation front, after that the average size of particles increases up to 5-6 nm during few microseconds.
