| Outline of Final Research Achievements |
High-performance X-ray microscopes are capable of providing breakthroughs in scientific fields such as materials science and biology because of the high penetrating power and short wavelength. However, there is still much room for development of X-ray lenses, which determine the performance of such microscopes, and research and development is being conducted in many countries around the world. In this study, we focused on reflective X-ray lenses to improve its microscope performance. We designed, simulated and fabricated deformable mirrors, and evaluated the performance. The developed deformable mirror was able to deform its shape with an accuracy of less than 1 nm, which was evaluated with an optical interferometer. The performance of the mirror was also evaluated by incorporating it into an X-ray focusing optical system, and it succeeded in correcting the wavefront aberration with an accuracy of λ/4.
