Investigations of fast processes by X-ray diffraction methods at the Siberian Synchrotron and Terahertz Radiation Center

Abstract

A unique instrumentation complex that includes wigglers, X-ray position sensitive detectors, diffractometers, and explosion chambers and enables a 73 ps X-ray diffraction time resolution (exposure time) has been developed at the Siberian Synchrotron and Terahertz Radiation Center, a research collaboration operating at the Budker Institute of Nuclear Physics, Siberian Branch of the Russian Academy of Sciences. A number of techniques have been developed and implemented with which nanosecond-resolution investigations of the nucleation and growth dynamics became possible for the first time for diamond and metal nanoparticles under explosion and shock wave conditions. Studies with millisecond resolution of the structural transformation dynamics of chemical reactions, investigations of the kinetics of self-propagating high-temperature synthesis, and obtaining information on the state of catalysts are also among the new possibilities developed.
