Compact e+e- Linear Collider (CLIC) -
Physics Study Group

CERN Organisers/steering: M. Battaglia A. De Roeck (convener) C. Detraz J. Ellis D. Schulte R. Settles G. Wilson

A high energy linear e+e- collider has been considered as a possible option for CERN as a post-LHC machine, see e.g. the report "Options for Future Colliders at CERN" by J. Ellis, E. Keil, G. Rolandi, (CERN-SL-98-004).

Within the framework of the "world-wide collaboration on Linear Colliders", the CLIC study explores the technical feasibility of beam acceleration by travelling wave structures at room temperature and high frequency (30 GHz) powered from a drive beam, the so-called Two Beam Acceleration scheme. The design luminosity for e+/e- collisions at a centre of mass of 3 TeV is 10^35 cm-2 sec-1. Polarisation, e-e- and gamma-gamma collisions are also considered as an option.

In February 2000 the Proposal for a Physics Study Group for the CLIC Multi-TeV Linear Collider was endorsed by the CERN management. The aim of the study group is to provide feedback from physics channel anlyses requirements to the CLIC machine study group, and in the longer term prepare the physics case for a Multi-TeV Linear Collider. A description of the aim can be found here .
