Vibration Measurements at the Swiss Light Source (SLS)

Vibration measurements have been carried out at the Swiss Light Source (SLS) site as part of a collaboration between the Paul Sherrer Institute (PSI) and the European Organization for Nuclear Research (CERN). The vibration level of the SLS floor and of some lattice elements of the SLS ring have been monitored under various experimental conditions. In particular, vibration spectra of lattice quadrupoles have been measured with a circulating beam and compared with the spectra of transverse beam positions, as measured with beampositionmonitors. This paper summarizes the results.
