Current status of neutron single crystal diffractometer SENJU at J-PARC/MLF

Kiyanagi, Ryoji  

SENJU is a single crystal neutron diffractometer at Material and Life science experimental Facility (MLF) in J-PARC. SENJU has been in the user operation for more than 7 years and yielded a number of scientific results out of inorganic, small molecular and magnetic materials. The unique features of SENJU include a wide coverage of solid angle realized by 37 2-dimensional detectors and a wide wavelength spectrum of neutrons, leading to very efficient measurements of Bragg reflections in a large Q-space. In addition to this unique characteristics, SENJU can accommodate a variety of sample environment devices such as a magnet and a furnace. Regarding to the data analysis, an in-house made software, STARGazer, is used to process the date measured on SENJU and we are now working to make STARGazer available through the web in order to provide a better experience for users.
