1W2B-Macromolecular crystallography

1W2B is a Macromolecular crystallography beamline operating in the 5-18 keV range, which locates at I quadrant of BEPC and 15# experimental hall. It’s mainly used to do X-ray diffraction and X-ray Absorption Fine Structure. It runs not only in the dedicated mode of synchrotron radiation but also in the parasitic mode.
