Gamma-gamma collider for bb (<12 GeV) energy region
Photon colliders based on high energy linear e+e- colliders are considered for many years but may appear only in very far future. In this talk I consider the gamma-gamma collider for the energy region below 12 GeV, suggested 1/2 year ago. This energy region (in gamma-gamma) is not covered by Super-B collider and its luminosity may be much higher than at the LHC. Such collider will be a nice place for application of modern outstanding technologies (linacs (SC, plasma-based), low-emittance electron sources, powerful laser systems, optical cavities). Same electron linacs can be used simultaneously for XFELs.
