Description

The electron-positron Future Circular Collider (FCC-ee) is a proposed high-luminosity lepton collider which will operate at energies ranging from 45.6 to 182.5 GeV. Each beam will radiate up to 50 MW of synchrotron radiation power, whose disposal poses obvious challenges for the machine and for the experiments. The lattice design upstream of the interaction point employs weak dipoles, within which the beam generates synchrotron radiation that could reach the detector and cause experimental background if not properly collimated. To mitigate this, a dedicated synchrotron radiation collimation system has been developed. This paper presents the performance of the FCC-ee synchrotron radiation collimation system in the interaction region in nominal conditions and during injection.
