Japan Atomic Energy Agency launched the Horonobe International Project (HIP) utilizing the Horonobe Underground Research Laboratory. The main objectives of this project are to develop and demonstrate advanced technologies to be used in repository design, operation and closure and a realistic safety assessment in deep geological disposal, and to encourage and train the next generation of engineers and researchers. In this review, an overview of the HIP is presented.

High-precision powder diffraction experiments under high pressure at the J-PARC PLANET beamline and recent results; Observation of hydrogen bond symmetrization in ice

Hattori, Takanori; Komatsu, Kazuki*

Nihon Genshiryoku Gakkai-Shi ATOMO, 66(12), p.618 - 622, 2024/12

https://doi.org/10.3327/jaesjb.66.12_618

The high-pressure neutron diffractometer PLANET is the first beamline dedicated to high-pressure neutron experiments in Japan. It was constructed at the Materials and Life Science Experimental Facility (MLF) in the Japan Proton Accelerator Research Complex (J-PARC) located at Tokai-mura in Ibaraki Prefecture. Energy-dispersive data measurement using pulsed neutrons, state-of-the-art optical instruments, and a high-pressure device enable us to analyze the structure of crystals, liquids, and glasses over a wide range of pressure and temperature with unprecedented accuracy. In this paper, we will show how this has been achieved and introduce the recently published results on the symmetrization of hydrogen bonds in ice.
