Power losses of a nominal CLIC beam in the ILC 20mrad extraction line

Strong beam-beam effects at the interaction point of a high-energy e+ e- linear collider such as CLIC lead to an emittance growth for the outgoing beams, as well as to the production of beamstrahlung photons and e+ e- coherent pairs. In this paper, we consider a nominal CLIC beam with an energy of 1.5 TeV and we estimate the power losses due to the disrupted beam, the beamstrahlung photons and the e+ e- coherent pairs along the 20 mrad extraction line considered for ILC, with scaled magnet settings. We show that such a design is not adapted for the CLIC conditions, in particular because of the too large amount of low-energy particles found in the disrupted beam and the coherent pairs.
