CLIC Conceptual Design and CTF3 Results

The international CLIC collaboration is carrying out an extensive R&D programme to prepare a multi-TeV electron-positron collider. This year the collaboration will produce a conceptual design report (CDR) to establish the feasibility of the technology. The CLIC concept will be introduced and the status of key studies of critical issues will be discussed, with a focus on the CLIC Test Facility 3 (CTF3), which is a small scale facility to produce and use a high current drive beam.
