With a circumference of approximately 91 km, the Future Circular electron-positron Collider, FCC-ee, aims for unprecedented luminosities at beam energies from 45.6 to 182.5 GeV. A major challenge is reaching its design performance in the presence of magnet misalignments and field errors. [...]

Selected advances in the accelerator design of the Future Circular Electron-Positron Collider (FCC-ee)
/ FCC Collaboration
In autumn 2023, the FCC Feasibility Study underwent a crucial “mid-term review”. We describe some accelerator performance risks for the proposed future circular electron-positron collider, FCC-ee, identified for, and during, the mid-term review. [...]

FCC-ee is a proposed lepton collider with a circumference close to 100 km to produce an unprecedented amount of luminosity. The FCC-ee optics tuning working group is addressing one of the most critical aspects of the FCC-ee, that is the recovery of the optics design performance in presence of realistic imperfections.

FCC-ee Lattice Design

Within the framework of the Future Circular Collider Feasibility and Design Study, the design of the electron-positron collider FCC-ee is being optimised, as a possible future double collider ring, currently foreseen to start operation during the 2040s. FCC-ee is designed to operate at four different energy stages, allowing for precision measurements: from the Z-pole up to above the ttbar-threshold. [...]

A special session at eeFACT’22 reviewed the electrical power budgets and luminosity risks for eight proposed future Higgs and electroweak factories (CCC, CEPC, CERC, CLIC, FCC-ee, HELEN, ILC, and RELIC) and, in comparison, for a lepton-hadron collider (EIC) presently under construction. We report highlights of presentations and discussions..

The Electron-Positron Future Circular Collider (FCC-ee)
/ Zimmermann, Frank (CERN) ; Benedikt, Michael (CERN) ; Oide, Katsunobu (Geneva U. ; KEK, Tsukuba) ; Raubenheimer, Tor (SLAC)
The Future Circular electron-positron Collider (FCC-ee) is aimed at studying the Z and W bosons, the Higgs, and top quark with extremely high luminosity and good energy efficiency. Responding to a request from the 2020 Update of the European Strategy for Particle Physics, in 2021 the CERN Council has launched the FCC Feasibility Study to examine the detailed implementation of such a collider.

The FCCee Pre-Injector Complex

The international FCC study group published in 2019 a Conceptual Design Report for an electron-positron collider with a centre-of-mass energy from 90 to 365 GeV with a beam currents of up to 1.4 A per beam. The high beam current of this collider create challenging requirements on the injection chain and all aspects of the linac need to be carefully reconsidered and revisited, including the injection time structure.
