The CLIC Physics and Detectors Conceptual Desing Report was completed in December 2011. The Compact Linear Collider (CLIC) is an e+e- collider operating at energies up to 3 TeV center-of-mass energy. The novel accelerating technology creates a train of bunches: 50 times per second, 312 bunches will cross with no more than 0.5 ns between bunch crossings. As a consequence of the intense beamstrahlung and hadronic background creation, the detectors have to cope with high occupancies. Reading out the 312 crossings in one go in between bunch trains, the interesting physics has to be disentangled from the overlapping background. To this end, the detectors are designed for high granularity particle flow, where reduction of the background relies on the ability to temporally and spatially separate energy depositions of the background from those from the physics interaction of interest. Full simulation and reconstruction analyses have been performed of so-called benchmark channels, to assess the performance of the detectors. The conclusion is that the ability to perform high precision physics at the 3 TeV e+e- collider is established.
