Description

The ESR storage ring at GSI unlocks the possibility for various atomic physics experiments with exotic beams. Therefore the operation of the ESR requires a wild change of parameters and cycles [1]. This may inadvertently push the machine tunes to cross a nonlinear resonance. This is particularly important especially in the process of deceleration, where the machine tune is moving quite notably along the cycle as measurements have shown, which could be one of the causes of significant beam loss.
Consequently, it is relevant to retrieve the actual resonance chart for the ESR. In this proceeding we discuss the adopted procedure, in the light of the ESR complexity and the limited applicability of the tune knobs in the machine settings, providing a first correction method.
