| Abstract | To improve electron beam stability and x-ray beam stability, the micron-order of magnitude vibrations of the quadrupole magnets have to be attenuated. A damping system to reduce quadrupole magnet vibrations, the so-called ‘damping link’, has been implemented at the ESRF storage ring. The damping link is a damping device using ViscoElastic material, installed between the girder and the floor. It is used to attenuate the resonant motion of the magnet girder assembly. Vibration tests on the magnet girders in the storage ring before and after installation of damping links show very satisfactory damping performance. On-line monitoring of electron beam motion, and of quadrupole magnets vibration have been carried out simultaneously during the operation of the ESRF machine. Measurement results show clearly vibration attenuation of the quadrupole magnets, significant improvement of electron beam stability. As a consequence, x-ray beam stability is also enhanced. 1 |
