PLANET is the first neutron powder diffractometer dedicated to high-pressure and high-temperature experiments in the world. The six-axis press designed for this beamline enables routine data collection at pressures and temperatures up to 10 GPa and 2000 ℃. In this article, we introduce how the PLANET had been constructed.

Minerals and rocks exhibit various isotope compositions depending on their origins and histories. In interpreting their isotopic variations, the equilibrium isotope fractionation factor is a key because it depends on the environment parameters such as temperature. Recent studies have shown that the effect of pressure on the isotope fractionation, which was considered negligible compared to temperature, is significant under the conditions of the Earth's interior. In this article we review recent advances in experimental studies to determine the isotope fractionation of iron and hydrogen at high pressure over several GPa, discussing their issues and future perspectives.

PLANET is a powder neutron diffractometer dedicated to high-pressure experiments. By combining the intense neutron source of J-PARC and the high-pressure devices designed for time-of-flight powder neutron diffraction, precise structure analysis of crystal, liquid, and amorphous solids is possible over wide pressure and temperature range of 0~20 GPa and 77~2,000 K. This beamline is effective for various studies in geophysics, planetary science, physics and chemistry. This paper overviews the beamline and introduces recent results obtained at PLANET.
