Six-axis multi-anvil press ATSUHIME is the press installed at high-pressure neutron beamline PLANET in J-PARC. It was constructed for neutron diffraction experiments. At present, PLANET is only the beamline wherein high-pressure and high-temperature experiments are routinely conducted. Thus, the six-axis press has been used in a wide range of scientific fields, such as physics, geoscience, and physical chemistry. In this talk, I introduce the design and performance of the press as well as recent neutron studies conducted using ATSUHIME.

Since hydrogen has a large scattering power for neutron, neutron diffraction can be an important tool in the investigation of hydrogen in minerals. The high-pressure neutron diffractometer PLANET in the MLF at J-PARC is equipped with a 6-axis type multi-anvil press to conduct high-temperature neutron diffraction experiments at high pressure. With the application of the multi-anvil assembly (MA) 6-6, experiments have been routinely performed. One of the advantages of using the MA6-6 is that the anvil gap is located at 2
= 90
, where the detector is located. However, the available pressure is currently limited below 12 GPa using MA6-6 with TEL size of 7 mm. It is necessary to expand the conditions to cover the mantle transition zone that is considered as an important reservoir of water. In this talk, I will present recent developments with applications of MA6-8 to expand the PT conditions in PLANET.
