| Research Abstract |
Applicability of electron beam induced luminescence (cathodoluninescence) measurement has been examined for characterization of chemical composition and crystallinity of ceramic functional materials developed for a fusion blanket. While characterization of materials with low crystallinity and low luminescence intensity is significantly important due to limitation in baking temperature of materials or damages in irradiation tests, it was confirmed that cathodoluminescence spectra can be obtained almost within 10 seconds with a spacial resolution of ~1 ・m by using a scanning electron microscope system. Microscopic luminescence measurements can be used effectively for ceramic coating development, study on irradiation effects, coolant circulation tests, etc.
