Abstract

Small errors in magnet alignment can be a significant source of transverse coupling in a storage ring. Beam offsets in the quadrupole and sextupole magnets at the Australian Synchrotron Light Source were measured using a LOCO based orbit response matrix analysis. The results were used to obtain an estimate of the offset in each magnet and these were then used to guide mechanical alignment efforts. A significant reduction in the uncorrected beam coupling was observed after these corrections, with a corresponding reduction in corrected coupling.
