The single crystal diffractometer, SENJU, which just became open for users, is the instrument designed to perform structure analyses under multiple extreme conditions even with tiny samples. Additional six detectors and T0 chopper were installed in order to improve the data collection efficiency and the background noise arises from the burst neutron. The solid angle covarage increased by 1.2 with the six new detectors, and significant reduction of the background noises were confirmed especially on the detectors at highest and lowest angles.
