Main parameters of TeV energy γp colliders

The main parameters of TeV energy γp colliders have been investigated for PHERA+LC, LHC+TESLA and LHC+e-Linac proposals in detail. In this research, the luminosity of γp collisions and the helicity of the high energy γ beam for these colliders are studied in terms of the distance between the conversion region and the collision point as well as γp invariant mass. The main design problems are also discussed.

New tool for “old” nuclear physics: FEL -nucleus colliders

Abstract A new method has been considered to investigate the scattering reactions with photons on fully ionized nuclei. To induce γ -nucleus collisions a free-electron laser and a heavy-ion synchrotron have been considered by bringing them together. Main parameters of the collider (especially LHC and HERA for the acceleration of nuclei) have been estimated. Rough calculations have also been made for the cross sections of the excited nuclei production. Finally, some design problems involving the collider have been considered.

based γp and γA colliders

Main parameters and physics search potential of gamma-p and gamma-A colliders, which will be available due to constructing the TESLA linear electron-positron collider tangentially to the HERA proton ring, are discussed.

Main Parameters of ILC-Tevatron Based Lepton-Hadron and Photon-Hadron Colliders

The construction of the ILC tangential to Tevatron ring will give opportunity to investigate electron-proton, positron-proton, electron-antiproton, positron-antiproton interactions at 1 TeV center of mass energy. The analysis of the lepton-hadron collisions in these energy region is very important both for understanding of strong interaction dynamics and for adequate interpretation of future LHC and VLHC data. In addition, ILC-Tevatron collider will provide a possibility to realize photon-hadron collisions in the same energy region using Compton backscattered laser photon off ILC electron beam. Main parameters of these colliders are estimated and their physics search potential is briefly discussed.
