Description
The SOLEIL II sextupoles are equipped with additional windings to provide normal and skew dipole corrections. Accurate modeling of these combined-function sextupole magnets are particularly challenging due to magnetic saturation, hysteresis, and internal cross-talk between channels. Based on 3D magnetic simulations, polynomial, interpolation-based, and neural-network models were developed to reproduce the saturation and cross-talk effects. These nonlinear models were validated on the first prototype magnet, providing preliminary confirmation of their reliability and demonstrating the feasibility of implementing sextupole-corrector magnets in the SOLEIL II storage ring.
