Research Abstract

This research project aimed at developing neutron diffraction measurements at high pressure using a intense spallation neutron source at J-PARC and clarifying crystal structures of hydrogen-bearing materials in the deep earth, interior of planets, and so on. We have developed novel neutron-focusing device for small samples under high pressure, new high-pressure instruments optimized for the intense neutron source. We have opened a new horizon for sciences on earth and planetary materials at high pressure.
