Vibration measurement of the SPring-8 storage ring

摘要

Importance of vibration problems increases with the smaller emittance of a storage ring for synchrotron radiation source. Vertical emittance of the SPring-8 storage ring is so small that effect of vibration to an electron beam can not be neglected. We thus studied the vibration of the SPring-8 storage ring. Measurements of beam oscillation and magnet vibration were done and the relation between them was investigated. Vibration source and propagation paths were also studied and the suppression method is discussed.
