Material sciences at ultra-high pressure using the strongest spallation neutron source

本研究项目旨在利用J-PARC的强散裂中子源开展高压中子衍射测量，并阐明地球深部、行星内部等含氢物质的晶体结构。我们研制了新型高压小样本中子聚焦装置，以及针对强中子源优化的新型高压仪器。我们为高压下地球和行星物质的科学开辟了新的视野。

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.
