AB - Fast correctors at NSLS-II storage ring has broad frequency response (~1kHz bandwidth), together with high accurate BPM 10kHz data makes the broadband fast orbit feedback realistic. With integrated NCO, beam orbit response can be precisely measured while driving the electron beam with AC current. Compared to the normal DC orbit response measurement, this method eliminates the measurement errors due to orbit drift. Accurately measured orbit response matrix can be used to characterize the machine lattice. Fast corrector frequency responses have been measured using the same method, by scanning the excitation frequency. This information can be used to optimize the fast orbit feedback control loop.
