The CERN linear collider

Abstract

The CERN study of an electron-positron linear collider is concerned with a two-beam system powered via a superconducting drive linac. The study pursues the development of suitable technologies for a 2 TeV (centre-of-mass) collider in the longer term but concentrates, now, on a 500 GeV first stage for which the two-beam system developed by us appears very suitable. Results are reported on the 30 GHz main linac, the drive beam and the final focus system.<>
