A new single crystal diffractometer SENJU is currently under construction in the MLF BL18 at J-PARC. SENJU is designed to collect diffraction data by use of a laboratory XRD specimen size, and aimed for a precise structure analysis under combined environmental conditions. Very wide variety of experiments will be performed, such as low-temperature, under magnetic field, high pressure, and so on. As for the most important component, detector system, is improved and optimized version of that of the iBIX system which is currently working well. The construction of SENJU will be completed in March 2011, and the instrument will be received the first neutron before summer maintenance period of 2011.
