Layout of the interaction region for electron proton collisions in the LHeC collider — •Tiziana von Witzleben1 and Bernhard Holzer2 — 1CERN, RWTH Aachen — 2CERN
The LHeC (Large Hadron electron Collider) project studies the design of a future electron-proton collider at CERN. Deep inelastic scattering collisions between electrons and protons will run in parallel to the standard HL-LHC (High Luminosity-LHC) operation. The electrons would be accelerated to a kinetic energy of 50 GeV in a tangential energy recovery linear collider and brought into collision with one of the 7 TeV proton beams of the HL-LHC. The design luminosity of the order of 1034 cm−2 s−1 requires strong focusing of both beams in a compact interaction region. The e-p collisions would take place simultaneously with the HL-LHC experiments ATLAS, CMS and LHCb, and possibly alternating with the ALICE experiment in a novel design under study. This, therefore, requires a highly precise beam optics for three beams: the two proton beams of the HL-LHC, as well as the additional electron beam. Initial design studies of the optics and orbits of the three beams have been performed to provide estimates for the aperture and gradients of the required magnets. Different strengths of the mini-beta quadrupoles, as well as different magnetic separations schemes have been modelled and the results will be presented.
