Description
The main objective in accelerator tuning is to correct linear optics. This involves adjusting a set of knobs, such as quadrupole strength and alignment errors, as well as addressing various calibration errors in beam monitors and other components. These errors can have a substantial impact on the performance of the accelerator. Using the full set of knobs might reduce the correction efficiency. Typically, it is advisable to prioritize the correction of large errors, as localizing them may enhance the overall efficiency of the correction process. The primary objective of localization is to identify and pinpoint potential sources of errors along with potential region. This paper explores and compares several commonly used error localization methods for the VEPP-4M model. By employing multiple methods, it becomes possible to cross-validate the results of the localization process.
