| Outline of Final Research Achievements |
Full-field hard X-ray microscopes are very promising due to capabilities of high-resolution, spectroscopic and quick observations. However, there are no microscopes without chromatic, wavefront and comatic aberrations, so that their applications are limited. In this research, developed four total-reflection mirrors, i.e., Advanced Kirkpatrick-Baez mirror optics, overcame the problem. Experiments at SPring-8 to evaluate the performances revealed that it achieved 50-nm spatial resolution without chromatic aberration. This is the first microscope that has 50-nm resolution without chromatic aberration. Furthermore, a full-field XAFS imaging system and full-field X-ray fluorescence microscope were developed. They could visualize distributions of chemical states and elements of a specimen as well as fine structure.
