In the following, we describe a method of shifting strengths of fast correctors to slow correctors, while the fast orbit feedback (FOFB) is turned on. This method has been developed to prevent saturation of the fast correctors, which results in degradation of the FOFB performance. At NSLS-II, we experimentally demonstrated a successful fast-to-slow corrector strength transfer. The maximal fast corrector current has been reduced from greater than 0.45 A to less than 0.04 A. At the same time, the beam orbit was stabilized within ±1 μm level, which is acceptable by the operational standard. Now, the method is ready for release to the routine operations.
