/ Oide, Katsunobu (KEK, Tsukuba) ; Benedikt, Michael (CERN) ; Blondel, Alain (Geneva U.) ; Bogomyagkov, Anton (Novosibirsk, IYF) ; Boscolo, Manuela (Frascati) ; Burkhardt, Helmut (CERN) ; Holzer, Bernhard (CERN) ; Koratzinos, Michael (Geneva U.) ; Levichev, Evgeny (Novosibirsk, IYF) ; Milanese, Attilio (CERN) et al.
The beam optics for the FCC-ee collider has been updated: (a) the layout is adjusted to a new footprint of FCC-hh, (b) the design around the interaction point is refined considering a number of machine-detecor interface issues, (c) the arc lattice is refined taking realistic magnet designs into account, (d) the β^{*} and betatron tunes are re-optimized according to recent results of the beam-beam simulations, and more. These changes make the collider design more realistic without performance degradation..

FCC-ee is a proposed high-energy electron positron circular collider that would initially occupy the 100-km FCC tunnel that will eventually house the 100 TeV FCC-hh hadron collider. The parameter range for the e⁺/e⁻ collider is large, operating at a cm energy from 90 GeV (Z-pole) to 350 GeV (t-tbar production) with the maximum beam current ranging from 1.5 A to 6 mA for each beam, corresponding to a synchrotron radiation power of 50 MW and a radiative energy loss varying from ~30 MeV/turn to ~7500 MeV/turn.

A design of beam optics will be presented for the FCC-ee double-ring collider. The main characteristics are 45 to 175 GeV beam energy, 100 km circumference with two IPs/ring, 30 mrad crossing angle at the IP, crab-waist scheme with local chromaticity correction system, and "tapering" of the magnets along with the local beam energy.

The FCC-ee study: Progress and challenges
/ Koratzinos, Michael (Geneva U.) ; Aumon, Sandra ; Bogomyagkov, Anton (CERN) ; Boscolo, Manuela (CERN) ; Cook, Charlie (CERN) ; Doblhammer, Andreas ; Härer, Bastian (CERN) ; Tomás, Rogelio (CERN) ; Levichev, Evgeny ; Medina Medrano, Luis (Unlisted, MX) et al.
The FCC (Future Circular Collider) study represents a vision for the next large project in high energy physics, comprising an 80-100 km tunnel that can house a future 100 TeV hadron collider. The study also includes a high luminosity e+e- collider operating in the centre-of-mass energy range of 90-350 GeV as a possible intermediate step, the FCC-ee. [...]

First Considerations on Beam Optics and Lattice Design for the Future Electron-Positron Collider FCC-ee
/ Härer, Bastian (CERN) ; Bogomyagkov, Anton (Novosibirsk, IYF) ; Holzer, Bernhard (CERN) ; Zimmermann, Frank (CERN)
The Future Circular Collider (FCC) study includes the design of a 100-km electron positron collider (FCC-ee) with collision energies between 90 GeV and 350 GeV. This paper describes first aspects of the design and the optics of the FCC-ee collider, optimised for four different beam energies. [...]

PERLE (Powerful ERL for Experiments) is a novel ERL test facility, initially proposed to validate choices for a 60 GeV ERL foreseen in the design of the LHeC and the FCC-eh. Its main thrust is to probe high current, CW, multi-pass operation with superconducting cavities at 802 MHz (and perhaps testing other frequencies of interest). [...]
