加速器中性子源を用いた水素貯蔵材料の物質科学研究

抄録

High intensity neutron total diffractometer (NOVA) was installed at BL21 of J-PARC/MLF and achieved the designated level of performance to study atomic distribution in various materials including liquids, amorphous and crystals. Short time and small sample measurements are feasible for averaged structure analysis, and the real space resolution is enough for local structure (Pair Distribution Function) analysis. Sample environments were prepared for auto sample change, low/high temperature and gas pressure, and time-transient hydrogen absorbing process was observed with the 𝘪𝘯-𝘴𝘪𝘵𝘶 hydrogen pressure measurement system. Three results obtained by NOVA are introduced.
