Averaged and Local Structure Analysis of Hydrogen Storage Materials by High Intensity Neutron Total Diffractometer, NOVA

Abstract

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 by high-flux pulsed neutron and low background at NOVA. Averaged and local structure analysis results of NaAlD₄-TiCl₃ and V-H systems are introduced.
