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.
