Residual Orbit Correction Studies for the FCC-hh

The FCC-hh (Future Hadron-Hadron Circular Collider) is one of the three options considered for the next genera-tion accelerator in high-energy physics as recommended by the European Strategy Group [*]. Preliminary studies have started to estimate the design parameters of FCC-hh. One of these studies is the calculation of the residual orbit in the arcs of the collider. This is very important for the evaluation of the alignment tolerances of the quadru-poles used in the arcs, the dimensioning of the correctors and of the beam screen. Moreover it has an impact on the dynamic aperture of the ring and the field tolerances of the arc multipoles. To perform the simulations, the beam transport code MADX has been used. Systematic studies of the residual orbit and of the correctors' strength de-pendence on the magnets misalignment or field errors are presented and discussed.
