Charged particles background due to electromagnetic processes at the VLEPP based Photon Linear Collider with ultimate luminosity

We have made preliminary estimates of charged particles background at the 100×100 GeV Photon Linear Collider with ultimate luminosity. The charged particles background due to electromagnetic processes is located mainly in the small-angle range of the detector. At large angles, the number of background particles is much smaller. Analysis of the background (at least, in the range under consideration) shows that background conditions for the VLEPP-based Photon Linear Collider are better than at the VLEPP electron-positron collider.
