  The Future Circular Collider (FCC) design study is aimed at assessing the
physics potential and the technical feasibility of a new collider with
centre-of-mass energies, in the hadron-hadron collision mode including proton
and nucleus beams, more than seven-times larger than the nominal LHC energies.
An electron-positron collider in the same tunnel is also considered as an
intermediate step, which would provide the electron-hadron option in the long
term. First ideas on the physics opportunities with heavy ions at the FCC are
presented, covering the physics of Quark-Gluon Plasma, gluon saturation,
photon-induced collisions, as well as connections with ultra-high-energy cosmic
rays.
