| Research Abstract |
In order to realize precise compositional analysis, we have developed a new type of X-ray detector for a transmission electron microscope based on a superconductor technology called “Transition-edge sensor”. It shows ten-fold higher energy resolution compare to a standard Si(Li)type X-ray detector. In this study, we constructed analytical method suitable for this new detector and applied to some metallic materials. We showed that this detector has very high sensitivity and can detect and analyze very small amount of segregation across the boundary.
