Research Group:

Earth and Planetary Science Group

Overview of Research Group, Goals and Purposes:

Many studies on physical properties of deep Earth materials have been done using high-pressure apparatuses, such as multi-anvil press and laser-heated diamond-anvil cell, at SPring-8. 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, radiography, tomography, or fluorescence measurements. Recently, application of new analytical techniques, such as X-ray Raman scattering, inelastic scattering, emission spectroscopy, M&oumi;ssbauer spectroscopy, have provided us new information about physical properties of the Earth’s 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.
1) To promote the discussion of the latest scientific results and related synchrotron techniques, and to inform the related matters to SPring-8 users and potential SPring-8 users in the field of the Earth and planetary science.
2) To promote discussion about future direction of Earth and planetary science combined with SPring-8 synchrotron including technical requirements to related beam lines, and to organize a working group for discussion of sciences and techniques in the future SPring-8 II.
3) To introduce new experimental systems and software for the potential users in the Earth and planetary science field, and to inform the status of related experimental equipments.
