The Future Circular Collider (FCC) study foresees the construction of a 90.7 km underground ring where, as a first stage, a high-luminosity electron-positron collider (FCC-ee) is envisaged, operating at beam energies from 45.6 GeV (Z pole) to 182.5 GeV (ttbar). In the FCC-ee experimental interaction regions, various physical processes give rise to particle showers that can be detrimental to machine components as well as equipment in the tunnel, such as cables and electronics.

Alternative solenoid compensation scheme for the FCC-ee interaction region
/ Ciarma, Andrea (Frascati) ; Burkhardt, Helmut (CERN) ; Boscolo, Manuela (Frascati) ; Raimondi, Pantaleo (Fermilab)
We present the optics design of the solenoid compensation scheme at the FCC-ee. The 2T solenoids from the experiments induce coupling on the beams, generating an increase on vertical emittance. [...]

The Future Circular Collider electron-positron (FCC-ee) is a proposed high-energy lepton collider that aims to reach unprecedented precision in the measurements of fundamental particles. Several beam related processes produce particles in the Machine-Detector Interface (MDI) region, which can adversely affect the measurements’ accuracy. [...]

Machine Induced Backgrounds in the FCC-ee MDI Region and Beamstrahlung Radiation
/ Ciarma, Andrea (CERN) ; Boscolo, Manuela (Frascati) ; Ganis, Gerardo (CERN) ; Perez, Emmanuelle (CERN)
The new design for the central chamber of the FCC-ee beam pipe has a reduced radius of R=10mm and length of L=18cm, allowing to have the inner layer of the Vertex Detector Barrel closer to the interaction point. The effect of the background induced occupancy due to Incoherent Pairs Creation (IPC), beam losses in the MDI area and Synchrotron Radiation are explored for the CLD detector, using the updated version of the Vertex Detector for the new central beam pipe.

The status of the energy calibration, polarization and monochromatization of the FCC-ee

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. [...]
