| Outline of Final Research Achievements |
We developed a novel non-destructive analytical technique that combines prompt gamma-ray analysis (PGA) and time-of-flight elemental analysis (TOF) by using an intense pulsed neutron beam at the Materials and Life Science Facility of Japan Proton Accelerator Research Complex. It allows us to obtain analytical results from the both methods at the same time. In addition, it can be used to quantify elemental concentrations in the sample, to which neither of these methods can be applied independently. A simple and accurate correction method for practical use was also developed for data processing in the TOF-PGA analysis. The effectiveness and the usefulness of the developed TOF-PGA method were confirmed by measuring of a composite reference sample. Moreover, its applicability was validated by analyzing of representative materials in several fields, such as cosmochemistry and environmental science.
