The FCC-ee lepton collider will be design to provide e⁺e^- collisions with centre-of-mass energies from 88 to 365 GeV. The centre-of-mass operating points with the most physics interest are around 91 GeV (Z pole), 160 GeV (W<sup+W^- pair-production threshold), 240 GeV (ZH production) and 340 - 365 GeV (ttbar threshold and above). The machine should accomodate at least two experiments operated simultaneously and deliver peak luminosities above per experiment at the ttbar threshold and the highest ever luminosities at lower energies.

The layout of the FCC-ee collider will be compatible with an energy frontier (order of 100 TeV) hadron collider (FCC-hh) that should be installed and operated after the end of the FCC-ee physics research programme.
