The Future Circular Collider project is built around two main pillars: the construction of 100 km lepton collider running at increasing energies from the Z-pole to the t-tbar threshold (FCC-ee) followed by a hadron collider in the same tunnel (FCC-hh) to explore unprecedented energy frontier.The realization of FCC-ee relies on a very challenging injector complex that should provide the highest ever realized source of positrons, which will serve the first phase of the collider operations (Z-pole). In this contribution the relevant aspects related to the damping of the high-emittance beam coming from the positron source and the transport of the damped beam within the different LINAC of the injector complex are presented and discussed..

Considerations for a new damping ring design of the FCC-ee pre-injector complex
/ Etisken, O (Kirikkale U. ; Frascati) ; Milardi, C (Frascati) ; Raimondi, P (SLAC ; CERN)
The current injector complex design of the FCC-e+e− project consists of e+/e− linacs, which accelerate the beams up to 6 GeV, a damping ring at 1.54 GeV, a pre-booster ring, accelerating the beam up to 16 GeV and a booster synchrotron ring integrated in the collider tunnel accelerating the beams up to the collision energies. The purpose of the damping ring is to accept the 1.54 GeV beam coming from the linac-1, damp the positron/electron beams and provide the required beam characteristics for the injection into the linac-2. [...]

Collective Effects Estimates for the Damping Ring Design of the FCC-ee
/ Etisken, Ozgur (CERN) ; Antoniou, Fanouria (CERN) ; De Santis, Antonio (Frascati) ; Milardi, Catia (Frascati) ; Zimmermann, Frank (CERN)
The current injector complex design of the FCC-e⁺e⁻ project consists of e⁺/e⁻ linacs, which accelerate the beams up to 6 GeV, a damping ring at 1.54 GeV, a pre-booster ring, accelerating the beam up to 16 GeV and a booster synchrotron ring integrated in the collider tunnel accelerating the beams up to the collision energies. The purpose of the damping ring is to accept the 1.54 GeV beam coming from the linac-1, damp the positron/electron beams and provide the required beam characteristics for the injection into the linac-2.

Estimates of Collective Effects for the FCC-$e^+e^-$ Pre-Booster Ring
/ Etisken, Ozgur (CERN) ; Antoniou, Fanouria (CERN) ; Çiftçi, Abbas Kenan (Izmir U. Economics, Izmir) ; Oide, Katsunobu (CERN ; KEK, Tsukuba) ; Papaphilippou, Yannis (CERN) ; Zimmermann, Frank (CERN)
The FCC-e⁺e⁻ injector complex needs to produce and to transport high-intensity e⁺ and e⁻ beams at a fast repetition rate for topping up the collider at its collision energy. Two different options are under consideration as pre-accelerator before the bunches are transferred to the high-energy booster: either using the existing SPS machine or designing a completely new ring.

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.

Damping bunch oscillations due to off-axis injection

In the FCC-ee pre-injector complex, a slightly modified SPS can serve as pre-booster. The baseline design foresees injecting the low-emittance electron and positron bunches off-axis into the SPS, and deploying strong wigglers to greatly enhance the radiation damping at the injection energy. [...]

Updates on alternative pre-booster ring design and wiggler magnet considerations of SPS for the FCC $e^{+}e^{-}$ injector

The Future Circular $e^{+}e^{−}$ Collider (FCC-$e^{+}e^{−}$) injector complex needs to produce and to transport a high-intensity $e^{+}e^{−}$ beam at a fast repetition rate for topping up the collider at its collision energy. Two different options are under consideration as pre-accelerator before the bunches are transferred to the high-energy booster: using the existing SPS and designing a completely new ring. [...]

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.

In the context of the FCC IS European study, which investigates the feasibility of a 100 km circular 𝑒+𝑒− collider for the future high-energy physics research, we present the status of the High Energy Booster (HEB) ring. In order to perform precision measurements of the Z, W and H bosons, as well as of the top quark, unprecedented luminosities are required. [...]
