Description
In fourth-generation light sources such as SIRIUS, tight orbit tolerances require accurate knowledge of BPM offsets with respect to the magnetic center of nearby quadrupoles. This work presents the implementation and experimental validation, at the SIRIUS storage ring, of the Parallel Beam-Based Alignment (PBBA) method proposed by X.~Huang. This method allows the simultaneous calibration of many BPMs. Simulations and machine experiments demonstrate that the method reduces the overall BBA time from several hours to a few minutes while preserving accuracy at the level of a few micrometers, making it practical for routine accelerator operation.
