First design of a post-collision line for CLIC at 3 TeV

As part of the Post-Collision Diagnostic Lattice task of the ILPS work-package of EuroTeV, we discuss a design of the beam line between the interaction point and the beam dump for CLIC with a center-of-mass energy of 3 TeV. The design is driven by the requirement to transport the beam and all secondaries, such as beamstrahlung photons and coherent pairs, to the beam dump with minimal losses. Moreover, we discuss the integration of novel diagnostic methods into the CLIC post-collision beam line, based on the detection of coherent pairs and monitoring the beam profile of the primary beam.
