The FCC-hh (Future Hadron-Hadron Circular Collider) is one of the three options considered for the next generation accelerator in high-energy physics as recommended by the European Strategy Group, and the natural evolution of existing LHC. Studies are ongoing about the evaluation of the various magnets mechanical errors and field errors tolerances in the arc sections of FCC-hh, as well as an estimation of the associated correctors strengths.
In this study an exploration of the possible tolerances is presented, the eventual impact on the correctors technological choice and on the beam screen design are discussed. A comparison with the LHC correction scheme is performed. Also the integration of the insertion regions (interaction region, collimation, etc) into the global correction scheme has been started and is discussed.
