SENJU, a TOF-Laue single crystal neutron diffractometer at the BL18 of MLF/J-PARC, was designed for precise crystal and magnetic structure analyses under extreme environments such as low-temperature, high-pressure and high-magnetic field. On-beam test measurements of 4K cryostat, superconducting magnet and high-pressure cell were carried out to evaluate the background from each device. All devices worked as planned on SENJU and single crystal neutron diffraction measurements under extreme conditions were successfully achieved at SENJU.
