    Oral presention (by invitation only)

    The FCC-ee collider requires continuous injection not only to maximize the average luminosity but also to ensure the stability of the beams by maintaining the charge of colliding bunches. The full energy booster will accelerate electron and positron beams to the collider energy which will then be injected into the collider ring.

    Several schemes are being studied but a conventional top-up...

    A good understanding of radiative Bhabha scattering at high energy e+e- colliders is important as it might become the limiting factor for the beam lifetimes. In this talk, the impact of beam-size effects will be presented, in particular the strong suppression of the radiative Bhabha scattering due to small lateral beam sizes at the interaction points. The resulting beam lifetime limits will be...

    A plethora of measurements at the FCC-ee crucially depend on efficient flavour tagging and precise flight distance measurements. To achieve this, the innermost piece of the FCC-ee detectors, the vertex detector, has to precisely locate the collision vertices, while adding only a minimal amount of material to the detector to limit multiple scattering deteriorating the detector...

    The RF systems of the FCCee are expected to be the primary consumers of power and energy. Moreover, the staged approach, ranging from Z to TTbar, necessitates modifications in the RF production method involving klystrons and solid-state devices, posing challenges for the powering infrastructure.

    This presentation will outline the RF powering requirements for each stage, including power...

    The FCC RF areas will be a major challenge from a cooling and ventilation point of view, as these points contain the highest concentration of thermal loads in the entire FCC complex. The total thermal load will depend primarily on the efficiency of the klystrons (currently being upgraded) and of the cryogenic systems. The location of the cryogenic systems will also determine the number and...

    The new Future Circular Colliders (FCC), including high-luminosity e⁺e⁻ collider, exploits the crab waist interaction scheme at interaction region (IR) with a beam crossing angle of 30 mrad. The small values of the beta functions at the interaction point requires strong and thin crab sextupole pair for chromaticity correction. Their location between 250 m and 700 m from the interaction region,...

    The FCC-ee will be installed in a 91 km long tunnel at around 200 m underground. The size of the project, the tunnel configuration and stability, the number of components to align and the alignment tolerances raise unprecedented challenges. From the manufacturing of the components to the relative alignment of these components during technical shutdowns, all the alignment steps are impacted. ...

    To reach integrated luminosity goals, the FCC-ee must be operational for minimum 80% of the scheduled 185 physics days each year. For comparison, the LHC achieved 77% in Run 2, 2016-2018. There are additional challenges in operation and maintenance of the FCC-ee due to its scale, complexity and ambitious technical objectives. Availability is therefore a significant risk to physics...

    In order to explore potential improvements to the current lattice design for FCC-ee, this work looks at the use of Combined Function Magnets (CFM) within the short straight sections of the arc cells. The use of CFMs introduces a change in the damping partition numbers. To avoid this it is necessary to maintain the values of the Synchrotron Radiation Integrals (I2 and I4), which are used to...

    The energy stored in Circular Electron and Positron Collider (CEPC) is in the order of MJ, which will make the beam pipe and other equipment broken once the beam loses control.

    One of the most fundamental measurements since the Higgs boson discovery, is its Yukawa couplings. Such a measurement is only feasible, if the centre-of-mass (CM) energy spread of the e+e- collisions can be reduced from ~50 MeV to a level comparable to the Higgs boson’s natural width of ~4 MeV. To reach such desired collision energy spread and improve the CM energy resolution in colliding-beam...
