Abstract :
The eigen vector method with constraint conditions (EVC) is the new orbit feedback scheme. When the global COD correction is made with the EVC, the local orbit correction can simultaneously be done without the deterioration of the global COD correction. In order to demonstrate the advantage of the EVC, we made the machine studies at the PF ring and the PF-AR, and the results successfully confirmed the advantage of the EVC.
