摘要
In the 3rd generation synchrotron light source,beside the orbit,air disturbance and ground vibration also could affect the position stability of photon beam in synchrotrons radiation measurement.In the condition of implementation of orbit feedback system at SSRF,the measured position stability of photon beam in synchrotrons radiation measurement station was presented in this paper.And then the improvement methods of position stability of photon beam were discussed.Finally the measured result was shown when the designed feedback system is implemented to improve the position stability of photon beam.
