Abstract :
It has been observed that the mechanical stability of some magnets had an influence on the closed orbit in the storage ring. In this paper, a mechanical shaker at a low vibration level was applied to the quadrupole magnet. The perturbation of the closed orbit was measured. The thermal induced distortion of magnet supporting structure was discussed. The motion of the BPM and quadrupole magnet were measured. Some examples of mechanical induced beam motion are discussed
