| Outline of Final Research Achievements |
Recently, aging of infrastructure is a problem, and the safety evaluation means of the infrastructure has been needed. When applying the positron annihilation lifetime measurement method, it may be able to detect metal fatigue at the early stage. Therefore it is desired of the realization. But it is difficult to apply this method because the conventional positron annihilation lifetime measurement requires two samples cut off.
In this study, by applying the method discovered in our laboratory, which does not require the cutting of samples, we have developed elemental technology to realize the measurement of the structure on-site.
