Overview of Research Group, Goals and Purposes:
Extensive studies on structures and physical properties of the materials in the deep Earth and planets have been done at SPring-8 by combining with high-pressure apparatuses such as a multi-anvil press and a diamond-anvil cell. In addition, numbers of important results have also been reported from synchrotron X-ray studies on extraterrestrial materials (meteorites, cosmic dusts, asteroid samples returned by the Hayabusa mission). In these studies, samples under high-pressure and high-temperature conditions or very small-scale samples have been analyzed by using X-ray diffraction, imaging and/or fluorescence measurements. Recently, developments of new combination of high-pressure experiment with X-ray Raman scattering, inelastic scattering, emission spectroscopy, and/or Mössbauer spectroscopy have provided new information about properties of the Earth and planetary materials under extreme conditions. Thus, synchrotron X-ray at SPring-8 is essential for the recent Earth and planetary sciences.
@Followings are the objectives of the gEarth and planetary science grouph:
- To discuss the latest scientific results and related synchrotron techniques for current and potential SPring-8 users in the field of the Earth and planetary sciences.
- To discuss about the future vision of Earth and planetary sciences using synchrotron X-ray measurements in SPring-8, such as new sciences and new techniques in the beamlines, with considering the current situation in other synchrotron facilities in the world.
- To introduce existing and new experimental systems and softwares in the beamlines for inviting potential users in the Earth and planetary science field.
