The Nb3Sn dipole design for the hadron machine option of the Future Circular Colliders enters in an intense and long R&D phase. As a result, more realistic dipole field quality evaluations are available for beam dynamics studies. In this paper we discuss the impact of the main dipole field quality on the first and second order design of the hadron machine and on its dynamic aperture.

"The design of the FCC-hh extraction systems is driven by the challenge to safely extract the 50 TeV proton beam. The new baseline for the beam dump system design foresees a fast single plane extraction realized by a highly segmented kicker system and a combination of SuShi (Superconducting Shield) and superconducting Cosine-Theta septa. In the dumpline a focusing structure is included to...

The FCC proton beams pose a severe challenge for the robustness of the beam dump and respective protection devices. Depending on the local beta-function, already a single 50 TeV bunch could induce damage in typical absorber materials currently employed in the LHC machine (e.g. Graphite or carbon composites). In order to safely absorb the FCC beams in a LHC-like dump or beam-intercepting...

Elisabeth Renner (Vienna University of Technology (AT))

Due to the high energy of the injected FCC-hh proton beam (1.3 or 3.3 TeV) a detailed evaluation of the injection design regarding potential failure cases is of major importance. Further attention has to be given to the fact that the injection is – as in LHC - located upstream of the side experiments.
