1W1A is a diffuse X-ray scattering beamline operating at 8.05 keV and 13.9 keV, which locates at I quadrant of BEPC and 12# experimental hall. It supplies double focusing monochromatic light and supports the structure researches on crystal and thin-film materials. It could run both in the dedicated mode of synchrotron radiation and in the parasitic mode.

Supported techniques:

　　  Coplanar X-ray diffraction/scattering

　　  Grazing incidence X-ray diffraction/scattering

　　  X-ray reflectivity/Non - specular X-ray scattering

　　  Grazing incidence small angle X-ray scattering (GISAXS)

Scopes:

　　  Defect in crystal materials

　　  Thin-film materials

　　  Surface/interface of multilayer film

　　 Nano-materials

Beamline equipments

　　 Huber five-circle diffractometer

　　 Detectors: NaI detectors, one-dimension position-sensitive detector;

　　 The system of control and data acquirement: SPEC
