The design of the interaction region of the positron-electron future circular collider must comply with various important constraints, imposed by high beam energy, high luminosity, need for polari-zation, and crossing scheme. An overview of the MDI design will be presented with a picture of the recent updates in the layout and ongoing studies. The status of the MDI activity will be summarised...

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 FCC-ee is a high-luminosity circular electron-positron which will have beam energies ranging from 45.6 ($\rm{Z}$ mode) to 182.5 GeV ($\rm{t\bar{t}}$ mode). In this presentation, the synchrotron radiation sources associated to each operating energy are described. The performances of the synchrotron radiation collimation scheme are detailed including the contribution from particles in the...

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 Future Circular electron-positron collider, FCC-ee, will require precise measurement of its beam energy. The proposed method of resonant depolarization has been successfully used at the Karlsruhe Research Accelerator (KARA) at the Karlsruhe Institute of Technology (KIT) for a long time. With a high amount of available machine physics days, short polarization times and flexible beam...

The FCC-ee will implement a crab-waist configuration, implying a very dense Machine Detector Interface (MDI), having accelerator components to be placed inside the detector. For the moment, a very elegant but complex design raises challenges, especially regarding the conditions near the components requiring alignment. Alignment sensors will need to be installed and operate in cryogenic...

The FCC-ee beam position monitors (BPM) is a non-invasive beam diagnostics system which consists out of ~2000 BPM pickups in each of the two main rings, plus read-out electronics and infrastructure. While most BPM pickups are located in the arcs, rigidly fixed at the quadrupole magnets, 3+3 BPMs are located in each of the interaction regions (IR) with particular challenging real-estate,...

Many key measurements at FCC-ee, such as the determination of the W-boson and top-quark mass and widths, require excellent knowledge of the collision energy. Resonant depolarisation, which will be the principal tool for calibration of the beam energy at the Z pole, will be much more demanding in the W+W- regime, and impossible at higher energies. Related challenges exist for the measurement...
