NOVA has almost 900 3-helium gas detectors for neutron diffraction measurements. Two Gas Electron Multiplier (GEMs) are installed as an incident-neutron and a transmission beam monitors. The performance of NOVA has been confirmed by several samples: structural analysis of crystalline and amorphous samples are demonstrated, the instrument background is low enough to measure S(Q) with the order of several ten mg for an hour. Typical S(Q) of silica glass (cylindrical rod, 20 mm long, and 7 mm diameter) is obtained up to 15 (1/${AA}$) for 1 sec and up to 35 (1/${AA}$) for 20 sec. These results show that NOVA is a powerful instrument for in situ dynamic investigation of rapid structural transformation in supercooled liquids and in hydrogen storage materials. Some of recent results of disordered materials on NOVA will be presented.
