Status of the FCC-ee lattice design and chromaticity correction scheme

FCC-ee is a new large-scale electron positron collider with 100 km circumference designed within the Future Circular Collider Study (FCC) at CERN. It is supposed to run at four different beam energies in the range of 45-175 GeV imposing different boundary conditions on the design. At high energies operation is limited by beamstrahlung and at low energies by the beam-beam threshold. To limit the impact of the respective effect different beam emittances need to be obtained by modifying the arc lattice. Furthermore the very ambitious interaction region requirements create very high chromaticity that has to be corrected with a sophisticated sextupole scheme. This talk will present the status of the lattice design and the chromaticity correction scheme.
