Title Photon production at the interaction point of the ILC
Abstract The intense beam-beam ffect at the interaction point of the International Lin- ear Collider (ILC) causes large disruption of the beams and the production of photons. These photons, arising dominantly through beamstrahlung emission, are problematic for the machine design as they need to be transported and dumped in a controlled way. In this work, we perform simulations of the beam-beam inter- action to predict photon production rates and distributions for the dfferent beam parameters considered at ILC. The results are expressed in terms of a set of cones of excluded power, allowing to define the beam-stay-clear requirements relevant for dfferent cases and contexts. A comparison is also made with theoretical expec- tations. The suggested photon cone half-opening angles are 0.75 and 0.85 mrad in the horizontal and vertical planes, respectively. These cones cover all machine energies and parameter sets, and include the low power Compton photons.
