Optics tuning of the FCC-ee

The Future electron-positron Circular Collider, FCC-ee,
is a proposed next generation collider aiming to provide large
luminosities at beam energies from 45.6 up to 182.5 GeV.
This collider faces a major challenge to deliver the design
performance in the presence of realistic lattice errors. A
commissioning strategy has been developed including ded-
icated optics designs, efficient beam-based alignment and
optics corrections based on refined optics measurements.
First specifications on main magnets, corrector circuits, and
instrumentation have also been investigated. A summary of
all these aspects is presented in this paper.
