Main parameters of $gamma p$ colliders

Abstract

Main parameters of TeV energy $gamma p$ colliders have been investigated for HERA+ SBLC, HERA+TESLA, HERA+e-linac, LHC+TESLA, LHC+CLIC and LHC+e -linac proposals. Luminosity of $gamma p$ collisions for these colliders are studied in terms of a distance between the conversion region and the collision point.
