High-Pressure and High-Temperature X-ray Diffraction Experiments at SPring-8 Beamline.

Abstract

SPring-8 is a third-generation synchrotron radiation facility that provides super-intense X-rays for basic and applied research in materials science. The bending magnet beamline, BL04B1 is one of the beamlines open for high-pressure and high-temperature research. A newly large volume high-pressure apparatus (SPEED-1500) was installed at BL04B1. This apparatus has a capability of generating pressures up to 40 GPa and a temperature of 3000 K by using a double-stage multi-anvil system with the sintered diamond anvils. High-pressure and high-temperature X-ray diffraction measurement using a combination of synchrotron radiation and SPEED-1500 makes it possible to investigate the constituent materials of the Earth's interior in the lower mantle.
