  • Patent number: 10145808
    Abstract: A micro beam generation unit capable of simultaneously capturing anisotropic images in a high signal-to-background ratio with a compact configuration and an X-ray small-angle scattering apparatus are provided. A micro beam generation unit 110 generates X-rays having a micro spot size, with which a sample is irradiated, in order to detect diffracted X-rays by a one-dimensional detector or a two-dimensional detector. The micro beam generation unit 110 includes a slit 115 that is provided on an X-ray optical path and reshapes X-rays into parallel beams, and two channel-cut monochromator crystals 117 and 118 that are arranged in arrangement of (+, ?, ?, +) and remove parasitic scattering of parallel beams reshaped by the slit. Accordingly, it is possible to simultaneously obtain anisotropic images in a high signal-to-background ratio with a compact configuration.
