Description

The upgraded Swiss Light Source storage ring, SLS 2.0, has employed a newly developed fast orbit feedback (FOFB) system since July 2026. This paper reports on the first year of operational experience and the resulting beam stability. We also detail the FOFB system design — including RF frequency correction and the decoupling of synchrotron oscillation frequencies within the FOFB bandwidth — and present measurements of the corrector magnet bandwidth.
