The neutron instruments suite, installed at the spallation neutron source of the Materials and Life Science Experimental Facility (MLF) at the Japan Proton Accelerator Research Complex (J-PARC), is reviewed. MLF has 23 neutron beam ports and 21 instruments are in operation for user programs or are under commissioning. A unique and challenging instrumental suite in MLF has been realized via combination of a high-performance neutron source, optimized for neutron scattering, and unique instruments using cutting-edge technologies. All instruments are/will serve in world-leading investigations in a broad range of fields, from fundamental physics to industrial applications. In this review, overviews, characteristic features, and typical applications of the individual instruments are mentioned.

The ZnS scintillator-based two-dimensional detector was developed for a time-of-flight neutron imaging with a high spatial resolution and a low -ray sensitivity. The detector is comprised of a thin ZnS scintillator with crossed wavelength-shifting-fibers (WLS fibers) arrays equipped with the fiber optic taper (FOT). The developed detector based on a neutron counting method has a high spatial resolution of less than 100 um (in FWHM) with a moderate count rate capability of several tens of thousands of cps. Of particular interest is its low -ray sensitivity of 10
. Imaging capabilities of the detector are demonstrated by using a high-intensity pulsed neutron beam at the Materials and Life Science Experimental Facility in the Japan Proton Accelerator Complex (J-PARC/MLF).

The detection efficiency of a ZnS-based neutron scintillator detector was evaluated as a function of the incident angle and the wavelength of a neutron. A pulsed neutron beam that has a wavelength from 1 to 8
was incident to the test detector that implemented a ZnS/LiF and ZnS/

scintillator that have thicknesses of 0.45 and of 0.20 mm, respectively. In each scintillator the detection efficiency increased as the incident angle increased for neutrons with a wavelength shorter than about 3. A comparison between the experimental results and the model fitting are presented.

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.

Neutron radiography is an effective water diagnostic tool for fuel cells. We continuously observed water behavior in a small type fuel cell under operation by high performance neutron radiography system using Neutron image intensifier. Water generated in the cell was initially accumulated in region of MEA and GDL, extending to a channel gradually. We will report and discuss about relationship between voltage drop and the water behavior in presentation.
