Structural Study of Hydrogen and Hydration by the IBARAKI Biological Crystal Diffractometer(iBIX)/Industrial Use

IBARAKI Biological Crystal Diffractometer(iBIX), a new neutron diffractometer for protein crystallography, was constructed as a next generation neutron source in J-PARC (Japan Proton Accelerator Research Complex) and it has begun operation since December 2008. During a fiscal year of 2009, 14 detector units, the basic part of data reduction software and an equipment of cryostream cooler to 20K became available, and measurements and structural analysis of an organic standard crystal were succeeded. Since 120kW accelerator operation in December 2009, neutron measurements for structural analysis of several crystals of inorganic, organic compounds and proteins including industrial users' have been carried out and some of these data sets have been analyzed to the degree that positions of the hydrogen and the hydrated water could be identified.
