Development and Construction Status of IBARAKI Biological Crystal Diffractometer (iBIX)

Abstract

Ibaraki biological crystal diffractometer (iBIX) is under construction at next generation pulse neutron source (Materials and Life science Facility, BL03) in J-PARC. The diffractometer is designed to cover the sample crystals which have their cell edges up to around 150Å, and to realize the efficiency of measurement which is more than 100 times larger than the present high performance diffractometers, BIX-3 and BIX-4 in JRR-3 reactor in JAEA. In this paper, the current status of the construction of iBIX will be reported with latest diffractometer design determined by using computer simulation.
