LHeC Ring-Ring Lattice Design — •Miriam Fitterer^1,2, Helmut Burkhardt¹, John M. Jowett¹, and Anke-Susanne Müller² — ¹CERN, Geneva, Switzerland — ²KIT, Karlsruhe, Germany

The Large Hadron Electron Collider (LHeC) aims at lepton-proton and electron-nucleus collisions with center of mass energies in the TeV range and a luminosity of around 10³³ cm⁻²s⁻¹. In order to achieve this, the existing 7 TeV LHC proton beam collides with a 50 to 140 GeV electron beam. Presently two options are considered as electron accelerator: the so called “linac-ring” and “ring-ring” option. Both options provide the possibility to operate in parallel with proton-proton or ion-ion collisions and imply either the construction of a linear accelerator with or without energy recovery or the installation of a new electron storage ring on top of the LHC. One of the principal challenges of the Ring-Ring option is the integration of the electron ring in the LHC tunnel. We present here a solution for the e-ring lattice compatible with the main LHC integration constraints.
