1W2A is a Small Angle X-ray Scattering beamline operating at a wavelength of 0.154nm, which locates at I quadrant of BEPC and 15# experimental hall. It supplies focusing monochromatic light and supports the structure researches by the SAXS pattern analysis. The measurable granularity range is 3~200 nm and the adjustable length of SAXS camera is 5m. This beamline runs not only in the dedicated mode of synchrotron radiation but also in the parasitic mode.
