Description
A beam-based alignment procedure is used to realign the beamt to the centres of the quadrupoles, enabling calibration of BPM offsets. Accurately determining these quadrupole centres is an important step that requires analyzing BPM data collected while modulating the nearby quadrupole and one or more corrector magnets in the ring. In this paper, several numerical methods to extract the quadrupole centres, with or without error analysis, are presented and their results are compared. This study is based on online experiments performed at Diamond.
