The new CLIC Test Facility CTF3 , built at CERN by an international collaboration, aims at demonstrating the feasibility of the CLIC scheme of multi-TeV electron-positron linear collider by 2010.
It is meant to demonstrate the technical feasibility of the key concepts of the novel CLIC RF power source, e.g., generation of high-charge, high-frequency electron bunch trains by beam combination in a ring using transverse RF deflectors and operation with a fully-loaded drive-beam accelerator.
CTF3 will also be used to test CLIC critical components and in particular will provide the 12 GHz RF power needed to test the main beam accelerating structures at the nominal gradient and pulse length (100 MV/m for 156 ns).
CTF3 is housed in the former LPI complex building. A layout of the facility in its final configuration is shown below.
