Beamstrahlung radiation at FCC-ee

Beamstrahlung is a dominant effect in high luminosity next-generation lepton colliders. The characterisation of the beamstrahlung radiation produced at the four working points of FCC-ee is presented, together with the tracking of these photons in the MDI region. As the emitted power results to be O(100kW ), the design of a dedicated extraction line is necessary in order to avoid energy deposition and secondary production on the beam pipe material.
