Abstract: (JACoW)
The international Future Circular Collider (FCC) study~[fccweb] aims at a design of p-p, \rm e⁺e⁻, e-p colliders to be built in a new 100~km tunnel in the Geneva region. The \rm e⁺e⁻ collider (FCC-ee) has a centre of mass energy range between 90 (Z-pole) and 375~GeV (t\bar{t}). To reach such unprecedented energies and luminosities, the design of the interaction region is crucial. The crab-waist collision scheme~[ref:cw] has been chosen for the design and it will be compatible with all beam energies. In this paper we will describe the machine detector interface layout including the solenoid compensation scheme. We will describe how this layout fulfills all the requirements set by the parameters table and by the physical constraints. We will summarize the studies of the impact of the synchrotron radiation, the analysis of trapped modes and of the backgrounds induced by single beam and luminosity effects giving an estimate of the losses in the interaction region and in the detector.
