Description

The control of nonlinear beam dynamics is essential for achieving the luminosity targets of FCC-ee, particularly in the presence of strong beam–beam interactions and machine imperfections. Resonance Driving Terms (RDTs) provide a systematic framework to characterize nonlinear dynamics and quantify the strength of resonances excited by nonlinear magnetic elements in the lattice. This contribution presents a sensitivity study of individual RDTs and their impact on beam losses, vertical emittance, and luminosity in FCC-ee, evaluated using tracking simulations including beam–beam interactions. The results establish a ranking of the relative importance of individual RDTs on the performance, providing guidance for future RDT-based correction strategies.
