High-pressure neutron diffractometer, PLANET, for observing hydrogen in materials under high-pressure and high-temperature conditions

Hattori, Takanori   

PLANET is a neutron powder diffraction beamline dedicated to high-pressure experiments, which was constructed at the Materials and Life Science Experimental Facility in J-PARC. The most characteristic feature is the capability of structure analysis on crystals, liquids and amorphous solids under high-pressure and high-temperature condition ( 10 GPa, 2000K) using a large multi-anvil press ATSUHIME specially designed for pulsed neutron diffraction experiments. Additionally, the high-pressure experiments can be performed at low temperatures ( 77 K) using various types of presses. Because of these unique characters, the PLANET is used in various fields of sciences, such as geophysics and materials science. The details will be introduced in the presentation.
