Outline of Final Research Achievements

We improved a pulsed neutron imaging method using energy analysis and promoted its applications. First, we improved a data analysis code and applied it to analyze martensite phase of quenched steels, a Japanese sword and a new material, and could develop a method to measure hardness non-destructively. CT methods were examined. A hydrogen storage material could be also studied. An imaging method of small angle scattering was developed. Quantitative analysis of a resonance absorption spectrum became feasible. Magnetic field was measured with good accuracy and the method was applied to a magnetic foil. Furthermore, we succeeded in phase contrast measurements using pulsed neutrons firstly in the world. A high counting rate detector and a camera type detector with short channel width of time of flight measurement were successfully manufactured.
