Structural studies of disordered materials using high-energy x-ray diffraction from ambientto extreme conditions

Abstract

High-energy x-rays from a synchrotron radiation source allow us to obtain high-qualitydiffraction data for disordered materials from ambient to extreme conditions, which isnecessary for revealing the detailed structures of glass, liquid and amorphous materials. Weintroduced high-energy x-ray diffraction beamlines and a dedicated diffractometer for glass,liquid and amorphous materials at SPring-8 and report the recent developments ofancillary equipment. Furthermore, the structures of liquid and amorphous materialsdetermined from the high-energy x-ray diffraction data obtained at SPring-8 are discussed.
