The Future Circular electron-positron Collider, FCC-ee, is designed for unprecedented precision for particle physics experiments from the Z-pole to above the top-pair-threshold. This demands a precise knowledge of the centre-of-mass energy (ECM) and collision boosts at all four interaction points and all operation energies. [...]

The Future Circular electron-positron Collider, FCC- ee, is designed for unprecedented precision for particle physics experiments from the Z-pole up to above the top-pair-threshold, corresponding to a beam energy range from 45.6 to 182.5 GeV. Performing collisions at various particle-physics resonances requires precise knowledge of the centre-of-mass energy (ECM) and collision boosts at all four interaction points. [...]

Centre-of-Mass Energy in FCC-ee
/ Keintzel, Jacqueline (CERN) ; Blondel, Alain (CERN) ; Shatilov, Dmitry (CERN) ; Tomás García, Rogelio (CERN) ; Zimmermann, Frank (CERN)
The Future Circular electron-positron Collider (FCC-ee) is designed for high precision particle physics experiments. This demands a precise knowledge of the beam energies, obtained by resonant depolarization, and from which the center-of-mass energy and possible boosts at all interaction points are then determined.

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. [...]

Damping ring and transfer lines of FCC-𝑒+𝑒− injector complex
/ Spampinati, Simone (Frascati) ; De Santis, Antonio (Frascati) ; Dutheil, Yann (CERN) ; Etisken, Ozgur (Kirikkale U. ; Frascati) ; Ramjiawan, Rebecca (CERN) ; Milardi, Catia (Frascati)
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..

The FCC-ee collider physics program requires a precise determination of the center-of-mass energy. The average energies of the two colliding beams can be measured by resonant depolarization (RDP) of polarized electron and positron bunches. [...]
