4W1A-X-ray Imaging

4W1A is a X-ray Imaging beamline and locate at IV quadrant of BEPC and 12# experimental hall. It’s mainly used for crystal morphology and Phase-contrast imaging. Since 2010, this beamline has set up a nano-imaging facility, the three-dimensional resolution of which has already achieved at 30nm. This beamline only runs in the dedicated mode of synchrotron radiation.
