Description

In this article, we overview the applications of neutron diffraction at high pressure to earth and planetary sciences. One of the main targets of mineralogy is to determine hydrogen position in hydrous minerals. Structures of hydrogen-bearing minerals and silicate melt at high pressure will contribute to understanding relationship between water and deep earth processes. Neutron is also a powerful tool to distinguish isoelectronic ions in minerals. To achieve these new scientific applications, we are going to construct a beamline dedicating to earth and planetary sciences at high pressure in J-PARC. The preliminary design of the beamline will be introduced.
