An ep collider based on proton-driven plasma wakefield acceleration

Recent simulations have shown that a high-energy proton bunch can excite strong plasma wakefield and accelerate a bunch of electrons to the energy frontier in a single stage of acceleration This scheme could lead to a future ep collider using the LHC for the proton beam and a compac electron accelerator of length 170 m, producing electrons of energy up to 100 GeV. The parameter of such a collider are discussed as well as conceptual layouts within the CERN accelerato complex. The physics of plasma wakefield acceleration will also be introduced, with the AWAK experiment, a proof of principle demonstration of proton-driven plasma wakefield acceleration briefly reviewed, as well as the physics possibilities of such an ep collider
