| Abstract |
The Taiwan Photon Source (TPS) had delivered the first synchrotron light on the last day of 2014 and is to open to the users from September 2016 after one and half years of commissioning and insertion devices installation. However, the instability is still an obvious problem to the beam quality and the deviation amplification factor of the magnets to the electron beam plays an important contribution role. Since the magnets are firmly installed on the girders and the contribution is mainly transferred from the girder vibration. This study tries to eliminate the obvious vibration frequencies amplitude exerted on the girder from outside sources such as the utility system with the PZT actuators installed on the locking wedges between girder and pedestals. By the amplitude and inverse phase searching iteration, some vibration frequency peaks in phase domain can be eliminated and the instability is also reduced.
