Following the decision to reduce the L∗ from 4.4 m to 4.1 m, the BeamCal had to be moved closer to the interaction point. Results of a study of how this affects the beamstrahlung and backward scattering backgrounds show that the e+e- pair background depositions from beamstrahlung at the BeamCal rises by 20%. The background from backscattered electrons and positrons in the inner pixel layers rises almost by a factor two, so does the number of photons in the tracker.
