Description
The Large Hadron-electron Collider (LHeC) is a proposed upgrade of the LHC at CERN. An Energy Recovery Linac (ERL) in racetrack configuration will provide an intense electron beam of up to 60 GeV energy to collide with the HL-LHC proton and ion beams. This configuration is also foreseen to be achieve higher energy $ep/e$A collisions eventually with those from the HE-LHC and the FCC-hh. Such configurations will yield electron-proton (nucleus) collisions with per nucleon centre-of-mass energies 1.3-3.5 (0.8-2.2) TeV and luminosities $\sim 10^{34(33)}$ cm$^{−2}$ s$^{-1}$, respectively. The talk describes the recent accelerator developments, an up-to-date configuration following optimisations of cost vs. energy, updates on the interaction region design and as well present the status of the 802 MHz, multi-turn ERL demonstrator facility PERLE at Orsay.
