Takashi Kimura,Soichiro Handa,Hidekazu Mimura,Hirokatsu Yumoto,Daisuke Yamakawa,Satoshi Matsuyama,Kouji Inagaki,Yasuhisa Sano,Kenji Tamasaku,Yoshinori Nishino,Makina Yabashi,Tetsuya Ishikawa,Kazuto Yamauchi +12 more
TL;DR: In this article, a bendable adaptive optical system that can be used in the hard X-ray region was developed to achieve highly precise control of the wavefront shape, and demonstrated the controllability of a wavefront of a 15 nm hard Xray nanobeam.
Journal ArticleDOI
Stitching-angle measurable microscopic-interferometer: Surface-figure metrology tool for hard X-ray nanofocusing mirrors with large curvature
Hirokatsu Yumoto,Hidekazu Mimura,Hidekazu Mimura,Soichiro Handa,Takashi Kimura,Satoshi Matsuyama,Yasuhisa Sano,Haruhiko Ohashi,Kazuto Yamauchi,Tetsuya Ishikawa +9 more
TL;DR: In this paper, an optical profilometer system for evaluating mirrors that are used for hard X-ray nanofocusing is proposed, which is based on a stitching interferometer that can determine stitching angles between adjacent local surface profiles.
Journal ArticleDOI
Stitching interferometric metrology for steeply curved x‐ray mirrors
Hirokatsu Yumoto,Hidekazu Mimura,Takashi Kimura,Soichiro Handa,Satoshi Matsuyama,Yasuhisa Sano,Kazuto Yamauchi +6 more
TL;DR: In this article, a relative angle determinable stitching interferometry (RADSI) method was proposed for hard x-ray nanofocusing mirrors, which consists of a microscope Michelson interferometer, and a large-area Fizeau interferer.
Journal ArticleDOI
Wavefield characterization of nearly diffraction-limited focused hard x-ray beam with size less than 10 nm.
Takashi Kimura,Hidekazu Mimura,Soichiro Handa,Hirokatsu Yumoto,Hikaru Yokoyama,Shota Imai,Satoshi Matsuyama,Yasuhisa Sano,Kenji Tamasaku,Yoshiki Komura,Yoshinori Nishino,Makina Yabashi,Tetsuya Ishikawa,Kazuto Yamauchi +13 more
TL;DR: A one-dimensionally focused beam with a width of 7 nm at 20 keV using a multilayer mirror is characterized and it is demonstrated that the wavefront can be determined precisely from multiple intensity profiles measured around the beamwaist.
Proceedings ArticleDOI
Development of adaptive mirror for wavefront correction of hard x-ray nanobeam
Takashi Kimura,Soichiro Handa,Hidekazu Mimura,Hirokatsu Yumoto,Daisuke Yamakawa,Satoshi Matsuyama,Yasuhisa Sano,Kenji Tamasaku,Yoshinori Nishino,Makina Yabashi,Tetsuya Ishikawa,Kazuto Yamauchi,Kazuto Yamauchi +12 more
TL;DR: In this article, a phase compensator for wavefront control of X-rays is presented, which is a 150 mm-long reflection mirror, the shape of which can be curved by adjusting the bias voltages of 36 piezoelectric plates attached to the mirror.
