Coherent X-ray Optics Laboratory
Research Areas
| The laboratory, located in the Harima institute, has two major missions. One is design and construction of the SPring-8 synchrotron radiation beamlines, in particular, their optical instrumentation. Another is the instrumentation for the advanced utilization of the synchrotron radiation as well as X-ray free electron lasers. This includes the developments of (i) optics cooling system with higher efficiency, (ii) fast x-ray photon detection system with sub-nanosecond resolution, (iii) meV-resolution x-ray energy analysis system, (iv) nano-radian range angle-resolved diffraction measurement system, (v) x-ray interferometry and its application to phase-sensitive imaging as well as photon-gravity interaction, and (vi) high-resolution x-ray imaging using diffraction (topography), interference (holography) and coherent scattering (diffraction microscopy). |  Chief Scientist Tetsuya ISHIKAWA (D.Eng.)  |
