Description
We have performed a detailed study of the power losses along the post-collision
extraction line of a TeV e+e- collider with a crossing angle of 20~mrad at the
interaction point. Five cases were considered: four luminosity configurations for ILC
and one for CLIC. For all of them, the strong beam-beam effects at the interaction
point lead to an emittance growth for the outgoing beams, as well as to the
production of beamstrahlung photons and e+e- coherent pairs. The power losses along
the extraction line, which are due to energy deposition by a fraction of the
disrupted beam, of the beamstrahlung photons and of the coherent pairs, were
estimated in the case of ideal collisions, as well as with a vertical position or
angular offset at the interaction point.
