  The LHeC provides an intense, high energy electron beam to collide with the
LHC. It represents the highest energy application of energy recovery linac
(ERL) technology which is increasingly recognized as one of the major pilot
technologies for the development of particle physics because it utilizes and
stimulates superconducting RF technology progress, and it increases intensity
while keeping the power consumption low. The LHeC instantaneous luminosity is
determined through the integrated luminosity goal. The electron beam energy is
chosen to achieve TeV cms collision energy and enable competitive searches and
precision Higgs boson measurements. The wall-plug power has been constrained to
100 MW. Two super-conducting linacs of about 900 m length, which are placed
opposite to each other, accelerate the passing electrons by 8.3 GeV each. This
leads to a final electron beam energy of about 50 GeV in a 3-turn racetrack
energy recovery linac configuration.
