Abstract

This article presents results of ground motion and magnet vibrations measurements at the Advanced Photon Source. The experiments were done over a frequency range of 0.1-100 Hz. Spectral power densities of vertical and horizontal motions of the APS hall floor and quadrupoles on regular supports were obtained. Magnet vibrations induced by designed cooling water flow and spectral characteristics of spatial correlation of the quadrupole vibrations at different sectors of the ring were also investigated. Amplitudes of the measured vibrations are compared with quad jitter tolerances in the APS
