TI - BPM Data Correction at SOLEIL
J2 - Proc. of IBIC2014
AB - In a synchrotron light source like SOLEIL, Beam Position Monitors (BPM) are optimized to have the highest sensitivity for an electron beam passing nearby their mechanical center. Nevertheless, this optimization is done to the detriment of the response linearity when the beam is off-centered for dedicated machine physic studies. To correct the geometric non linearity of the BPM, we have applied an algorithm based on a boundary element method. Moreover the BPM electronics is able to provide position data at a turn by turn rate. Unfortunately the filtering process in this electronics mixes the information from one turn to the neighboring turns. An additional demixing algorithm has been set-up to correct this artefact. The paper reports on performances and limitations of those two algorithms that are used at SOLEIL to correct the BPM data.
