Orbit Feedback System for the MAX IV 3 GeV Storage Ring

• The paper gives an overview of the planned orbit correc- tion system for the 3 GeV storage ring at the MAX IV lab- oratory, a light source facility currently under construction in Lund, Sweden[1, 2]. The ring will have a vertical beam size in the 1-4μm range in the insertion device (ID) straight sections depending on coupling[3], which places high re- quirements on the orbit stability. To meet this the ring will be equipped with 200 beam position monitors (BPMs) and two different sets of corrector magnets, which will be used by two separate orbit feedback loops; a slow orbit feedback (SOFB) loop to handle misalignments and drifts and a fast orbit feedback (FOFB) loop to reduce beam jitter. The pa- per also includes a brief description of the various engi- neering boundary conditions on the orbit feedback design for the MAX IV 3 GeV storage ring.
