New concept for a CLIC post-collision extraction line

Strong beam-beam effects at the interaction point of a high-energy e⁺e^- linear collider such as CLIC lead to an emittance growth for the outgoing beams, as well as to the production of beamstrahlung photons and e⁺e^- coherent pairs. We present a conceptual design of the post-collision line for CLIC at 3 TeV, which separates the various components of the outgoing beam in a vertical magnetic chicane and then transports them to their respective dump.
