Description

The Future electron-positron Circular Collider (FCC-ee) is a proposed lepton collider for high-energy particle physics succeeding the High-Luminosity Large Hadron Collider (HL-LHC). Its ambitious design goals demand excellent orbit and optics control and, therefore, set strict limits on alignment tolerances. Beam-based alignment (BBA) is used to relax the mechanical alignment tolerances by determining the offset between the magnet and the measured beam position. Orbit correctors steer the particle beam towards the determined positions of the magnetic centre and thus reduce the effective quadrupole misalignment. A parallel BBA technique is compared for the Global Hybrid Correction (GHC) and Local Chromaticity Correction (LCC) lattices for FCC-ee using Xsuite simulations.
