BEAM BASED ALIGNMENT FOR THE STORAGE RING MULTIPOLES OF SYNCHROTRON SOLEIL

First beam-based alignment (BBA) measurements have been carried out during the commissioning of the SOLEIL Storage Ring that started in May 2006. The results will allow calibrating the zero reading of the 120 Beam Position Monitors (BPMs) with respect to the magnetic centre of the adjacent quadrupoles or sextupoles. We plan to use two different BBA methods related to each multipolar magnet BPMs being either adjacent to quadrupoles or sextupoles. Moreover, multiple different experiments will favour results cross-checking. As we did not have enough time to validate our algorithms, we present here only the automated methods we plan to apply and the MATLAB user interface dedicated to BBA.
