Research Area:Fundamental Characterization
Beamline:BL04B1, BL10XU, BL35XU, BL22XU, BL20B2 etc.
Overview of Research Group, Goals and Purposes:
Extensive studies on physical properties of materials in the deep Earth and planets have been done at SPring-8 utilizing high-pressure apparatuses such as a multi-anvil press and a diamond-anvil cell. Important results have also been reported from studies on extraterrestrial materials (meteorites, cosmic dusts, asteroid samples returned by the Hayabusa explorer). In these studies, samples under high-pressure and high-temperature or very small-scale samples have been analyzed based on X-ray diffraction, imaging and fluorescence measurements. Recently, application of new analytical techniques, such as X-ray Raman scattering, inelastic scattering, emission spectroscopy, Mössbauer spectroscopy, have provided us new information about physical properties of the Earth and planetary materials under the extreme conditions. Therefore, synchrotron X-ray at SPring-8 is the necessary tool on the cutting edge of the recent Earth and planetary sciences.
Based on the present circumstances described above, objectives of the "Earth and planetary science group" are the following.
