Abstract：
The beam horizontal orbit at Hefei Light Source (HLS) was drifting all along while the storage ring was operating. To study this phenomenon, the displacement and the temperature variation of the BPM chamber were measured. By analyzing the measurement results, the main reason that explained the drifting phenomenon was found. The vacuum chamber following the dipole magnets was heated by the synchrotron light, which caused the increasing of the chamber surface temperature. The variation of the chamber temperature was
the main reason why the BPM chamber held the horizontal displacement. To suppress the orbit drifting, a compensation method of BPM movement was proposed and its experimental results were given.
