Times Cited Count：7 Percentile：50.3(Instruments & Instrumentation)Neutron imaging by color center formation in LiF crystals was applied to standard samples such as a sensitivity indicator (SI) for neutron radiography. The SI was exposed to 5 mm pinhole collimated thermal neutron beam with a LiF crystal and a neutron imaging plate (NIP) for 120 min in JRR-3 thermal neutron radiography facility. The image in NIP was read out with a readout resolution of 50 
m. The image of SI in LiF crystal was read out with pixel size of 1.38 m using a laser confocal microscope. All gaps were clearly observed in the images for both LiF crystal and NIP, but small holes were not recognized for NIP. The experiment showed that LiF crystals had excellent characteristics as neutron imaging detectors such as high sensitivity, high spatial resolution, wide dynamic range and so on. In the paper, detailed characteristics of LiF crystals are compared with those of other neutron imaging detectors: NIP, a combination of fluorescent converter and cooled CCD camera.

Influence of powder size on the characteristics of Gd
OS and BO
/ZnS(Ag) type scintillators were investigated. We prepared GdOS powder with 3.1, 6.1, and 10.1 micro-meter in mean diameter and coated with a binder on an Al plate. Beam tests were carried out at neutron radiography facility in JRR-3 and HANARO. In the results, the intensity of scintillation light is increased with increasing the diameter. The results of BO type will be also reported in this presentation.

Neutron radiography is an effective water diagnostic tool for fuel cells. For observation of water distribution in small region in fuel cells, improvement of spatial resolution of neutron radiography system is required. We fabricated the small aperture system for improvement of collimator ratio on Thermal Neutron Radiography Facility (TNRF) in JRR-3. In characteristic tests, better sharpness images were obtained by small aperture system compared with conventional radiography system.

Simulant material of Cs-bearing particle was synthesized from the melted glass of which composition was selected based on the composition of the Cs-bearing particle. The relationship between the nucleation behavior of Franklinite (ZnFeO
) and cooling speed was studied. The possibility of the formation of Franklinite phase through spinodal decomposition was also evaluated.
