| Outline of Final Research Achievements |
Various analysis methods using x-rays such as x-ray photoemission spectroscopy and x-ray absorption spectroscopy are indispensable for developing advanced materials. One of key technologies for improving the performance of these methods is x-ray focusing.
The purpose of this study is the development of mirror-based focusing soft x-rays whose wavelength ranges are from 1 nm to 10 nm.By employing a symmetric rotational mirror, it is possible to focus soft x-rays into a nanometer size. In this study, we improve the figure accuracy of the mirror and proposed two-stage soft x-ray focusing system in which a ring-focusing mirror and a symmetric rotational mirror are installed. We performed basic research on soft x-ray focusing with a mirror using high order harmonic generation source and constructed the two-stage soft x-ray focusing system at a beamline of SPring-8. We confirmed the size of soft x-ray focused beam is less than 200 nm at a wavelength of 3 nm .
