/ 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..

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.

Combined Operation and Staging Scenarios for the FCC-ee Lepton Collider

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.

Several Topics on Beam Dynamics in FCC-ee
/ Oide, Katsunobu (KEK, Tsukuba) ; Aumon, Sandra (CERN) ; Charles, Tessa (CERN) ; El Khechen, Dima (CERN) ; Shatilov, Dmitry (Novosibirsk, IYF) ; Tydecks, Tobias (CERN)
The FCC-ee is a double-ring $e^+e^-$ collider to be installed
in a common tunnel of∼ 100km circumference, as a po-
tential first step before the FCC-hh hadron collider. Several
studies on the beam dynamics at FCC-ee: low emittance
tuning, dynamic aperture, beam blowup with/without beam
beam, are introduced in the paper..

Progress in the FCC-ee Interaction Region Magnet Design

The design of the region close to the interaction point of the FCC-ee experiments is especially challenging. The beams collide at an angle (±15mrad) in a region where the detector solenoid magnetic field is large. [...]

The FCC-ee study: Progress and challenges

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. [...]

Bunch Schedules for the FCC-ee Pre-injector
/ Ogur, Salim (CERN ; Bogazici U.) ; Oide, Katsunobu (CERN ; KEK, Tanashi) ; Papaphilippou, Yannis (CERN) ; Shatilov, Dmitry (Novosibirsk, IYF) ; Zimmermann, Frank (CERN)
The latest design of the Future Circular electron-positron Collider (FCC-ee) foresees a luminosity per interaction point above 2.0·10³⁶/cm²/s for operation at the Z pole. The filling from zero current occurs in collision to profit from the bunch lengthening due to beamstrahlung (so-called bootstrapping). [...]

Towards a Preliminary FCC-ee Injector Design

The Future Circular Collider-ee aims to get high luminosity which mainly relies upon high charge and low geometric emittance in the collider. The FCC-ee is a future project of CERN to operate as Z, W, H and tt factories with varying energies between 45.6 to 175 GeV. [...]

Overall Injection Strategy for FCC-ee

The Future Circular electron-positron Collider (FCC-ee) requires fast cycling injectors with very low extraction emittances to provide and maintain extreme luminosities at center of mass energy varying between 91.2-385 GeV in the collider. For this reason, the whole injector complex table is prepared by putting into consideration the minimum fill time from scratch, bootstrapping, transmission efficiency as well as store time of the beams in synchrotrons to approach equilibrium emittances.
