Description

In the SOLEIL II upgrade project, combined-function sextupoles are equipped with additional windings to provide dipole and skew quadrupole corrections. Magnetic saturation, hysteresis, together with cross-talk between the correction channels, make accurate modeling and trimming of such magnets particularly challenging. A hybrid approach has been developed to describe the nonlinear behavior of the sextupole-corrector magnets. Based on 3D magnetic simulations, a neural network model was trained to reproduce the saturation and cross-talk effects among the magnet channels. To account for the hysteresis behavior, a Preisach model was also integrated into the framework. The combined model was validated on a prototype magnet, providing preliminary confirmation of the model’s reliability and the feasibility of applying these magnets in the SOLEIL II storage ring.
