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.

The FCC-ee is a high-luminosity, high-precision circular collider to be constructed in a new 100 km tunnel in the Geneva area. The physics case is well established and the FCC-ee operation is foreseen at 91 GeV (Z-pole), 160 GeV (W pair production threshold), 240 GeV (Higgs resonance) and 365 GeV ($t \bar{t}$ threshold).

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 Design of Beam Optics for FCC-ee Collider Ring*
/ 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..

For the Future Circular Collider (FCC-ee), particular attention is drowned to the crucial role of the positron source. Two positron production schemes are considered for the FCC-ee: conventional and crystal-based (hybrid), implying the use of channeling radiation in the oriented crystals. [...]
