| Outline of Final Research Achievements |
In this study, we aimed to realize a high-performance full-field X-ray microscope by developing the world's first reflective X-ray lens (Advanced Kirkpatrick-Baez imaging mirror), which is a key device to improve efficiency and spatial resolution.
The reflective lens was designed and simulated from various perspectives, and an optimized prototype was fabricated. The reflective lens was developed by coating it with multilayer for 8 keV X-rays. Its performance was evaluated by constructing an X-ray microscope at SPring-8, and it could resolve a 20 nm structure. The world's smallest resolution was achieved in an X-ray microscope using a reflective lens.
