AB  - The performance of monochromator is crucial to the performance of a beamline, especially for a 4th genera-tion synchrotron light source. To find out the perfor-mance of the monochromator prototype built for the HEPS project, it was tested at a wiggler beamline of BSRF with water cooling. The cooling of the crystals was measured by rocking curve broadening at different energy and cooling seems to be not enough due to indium foils. The repeatability in 1 hour was about 0.1 eV. The energy drift in 9 hours after the beam hit the beam-line was 0.4 eV at the Cu K edge. The short-term stability was tested with synchrotron beam under various cooling condition, and results between 4.4 nrad to around 400 nrad were observed. In conclusion, some performances are satisfying, but further improvements should be carried out in the future.
