Optics Characterization and Correction at the PEP-II
- SLAC
The linear optics of both the high energy ring (HER) and low energy ring (LER) for SLAC's PEP-II B-Factory were characterized with two algorithms: analysis of the measured closed orbit response matrix and analysis of betatron phase advance measurements. The results of the two analyses were in good agreement. When the HER was first run in a low {beta} optics in autumn 1997, the measured {beta} functions showed more than a factor of two discrepancy from the design. The source of the optics distortion was diagnosed and corrected using these methods.
