A new single crystal time-of-flight neutron diffractometer has been installed at BL18 of the Materials and Life Science Experimental Facility of J-PARC. The diffractometer “SENJU” was designed for precise crystal and magnetic structure analyses using a small crystal less than 1 mm under multiple extreme environments such as low-temperature and high-magnetic field [1]. The first neutron beam was delivered to the sample position on March 5, 2012. Subsequently, the hardware and software of SENJU have been checked and confirmed that they worked fine. At the same time, diffraction experiments of several organic and inorganic crystals have been done using NaCl, 12CaO!7Al2O3 (Fig. 1), and so on. In these measurements, Bragg reflections in the high-Q region (d-spacing < 0.5 A) were clearly observed and analyzed successfully. In this presentation, we will show the instrument design and performance evaluation of SENJU in detail.
