Description
The Large Hadron electron Collider (LHeC) is the proposal to deliver electron-proton/nucleus collisions at CERN using the LHC beams and a 50 GeV electron beam from an Energy Recovery Linac. While initially foreseen [1] for concurrent electron-hadron and hadron-hadron operation, a standalone electron-hadron operation phase has been proposed [2] in view of the current LHC schedule. Thus, the LHeC becomes a bridge from the HL-LHC to the next flagship at CERN, and one of the possible projects in the 2026 Update of the European Strategy for Particle Physics [3], were the FCC-ee as plan A not feasible.
In this talk we review the status of the design of a detector for the LHeC, and its extension to the FCC-eh. We present the present technology choices with their expected performance. We also analyse the possible synergies with future projects like ePIC, ALICE3 and detectors for $e^+e^-$ colliders. Finally, we review the feasibility and cost of such a detector.
