CLIC progress towards Multi-TeV Linear Colliders.

New parameters of an e+/e- Linear Collider based on CLIC technology for a luminosity of 7∙1034 cm-2s-1 at a nominal energy of 3 TeV are presented. They are derived in part from the very successful tests and experience accumulated in the CLIC Test facility, CTF2. A new and ambitious test facility, CTF3, presently under construction at CERN in an international collaboration of laboratories and institutes, and aimed at demonstrating the key feasibility issues of the CLIC scheme, is described.
