Status of the Small-Angle Neutron Scattering Station at the Beijing Synchrotron Radiation Facility

Abstract

Beamline 4B9A at the Beijing Synchrotron Radiation Facility provides focused monochromatic radiation in an energy range of 3–10 keV. The small-angle X-ray scattering (SAXS) station that is located at the end of the beamline is equipped with a SAXS camera, a position-sensitive detector, an on-line data-acquisition and control system and an alignment carriage. Studies in molecular biology and materials science have been performed at the station. Some results of SAXS studies of biomembranes are described. The experiments confirm that the angular resolution is better than 0.5 mrad with this setting.
