Description

The Large Hadron-electron Collider is the opportunity for DIS at the TeV scale in the HL-LHC era. An energy recovery linac in racetrack configuration would provide 20-60 GeV electrons to collide with the HL-LHC hadron and nuclear beams, providing instantaneous luminosities around $10^{34}$ and $5\cdot 10^{32}$ cm$^{-2}$s$^{-1}$ per nucleon respectively. It would extend the kinematic $x-Q^2$ plane down in $x$ and up in $Q^2$ by around two and four orders of magnitude in $ep$ and $eA$ respectively. A comprehensive physics programme on precision QCD, top, EW , Higgs, BSM and nuclear physics would be achievable with such machine. In this talk we will review accelerator, physics and detector aspects of the proposal, following the update [1] of the 2012 CDR [2]. Besides, the studies on the recent proposal of a detector in IP2 able to study both ep/A and pp/pA/AA collision will be presented, including a new detector and IR design [3].
