Research Abstract

The technical developments for the high-pressure neutron diffraction, which is performed with 6-rams large-volume press installed at BL11 (PLANET) in J-PARC, have been pursued in the present project. The fundamental technique has been established and the preliminary data on some hydrous silicate glasses were taken successfully under high-pressure conditions.
