Passive vibration damping of the APS machine components
- Argonne National Laboratory, Argonne, Illinois 60439 (United States)
The accelerator and beamline components of the Advanced Photon Source have stringent vibration criteria in order to meet the beam stability requirements. For instance, the vibration amplitude of the storage ring quadrupoles is restricted to 0.11 {mu}m (rms) over a frequency range of 4{endash}50 Hz. Damping pads, consisting of thin viscoelastic films sandwiched between stainless steel plates, have been designed for passive vibration damping. Results presented in this paper show that the damping pads under the storage ring girder-magnet assemblies reduced the vibration amplification factor Q from over 100 to 8. The broad band rms motion of the magnets was reduced by a factor of 2.5 to 3. Preliminary results for a monochromator housing show a potential use of such damping pads for vibration control of beamline components. Radiation and creep effects on the damping pads{close_quote} performance are considered. {copyright} {ital 1996 American Institute of Physics.}
