Description
The control of the optics in the Future Circular electron–positron Collider (FCC-ee) is a challenging but crucial task for meeting its performance goals. Lattice imperfections, such as magnet misalignments and field errors, introduce distortions in the phase advance between the Interaction Points (IPs), which could affect the Dynamic Aperture (DA) and degrade luminosity, particularly in the presence of strong beam–beam interactions. This work presents simulation studies of modeling such imperfections, quantifying their impact on the optics and in particular on the phase advance between the IPs, and developing correction schemes aimed at restoring the nominal phase advance. Implications for the DA and beam quality are discussed.
