At the JAERI, we have constructed several high-resolution neutron diffractometers dedicated to biological macromolecules (called BIX-type diffractometers), which use a monochromatized neutron beam and a neutron imaging plate detector. In this paper, we review several interesting results regarding hydrogen positions and hydration in proteins, obtained using the two BIX-type diffractometers in JAERI. The general subject of neutron protein crystallography has been reviewed by several authors, and several selected topics have been discussed.

As a new candidate for raw materials of a neutron imaging plate, characteristics of a SrBPO:Eu phosphor that has boron (B) in the base matrix as a neutron converter have been investigated. The phosphor has a strong merit that it generates photostimulated luminescence of 390 nm by illumination of red laser light after neutron irradiation. The emission and excitation wavelengths were the same as those of commercially available neutron imaging plate. Therefore, the authors have fabricated neutron imaging plates by painting the phosphor on Al plates. Neutron imaging experiments using the fabricated imaging plates were carried out with a commercially available image reader. A Li block was used as a camera subject in the experiments. As a result of the experiments, it was confirmed that the neutron image was clearly obtained, though the intensity of the image was not so high. The position resolution of 0.2 mm was obtained when the readout resolution of 50 
m in the reader was used.

Neutron diffraction provides an experimental method of directly locating hydrogen atoms in proteins and nucleic acids, and the development of the neutron imaging plate (NIP) became a breakthrough event in neutron protein crystallography. A high-resolution neutron diffractometers dedicated to biological macromolecules (BIX-3, BIX-4) with the NIP have been constructed at Japan Atomic Energy Research Institute. The detailed structure of the diffractometer and the systematic procedure of the neutron diffraction experiment from the crystallization of a large single crystal to the data collection and the data processing, and the future prospect of the neutron diffractometry in proteins will be presented.
