CLIC Test Facility


CLIC is an e+e- linear collider project operating at energies from 1 TeV to 5 TeV in the center of mass, with luminosities of the order of 1035 cm-2s-1, devoted to particle physics experiments in the post LHC era. The project is based on a two beam acceleration scheme in which the very high energy of the main beam is reached in high gradient (150MV/m) 30 GHz RF structures powered by the energy extracted from the drive beam. This is presently the only scheme which allows reaching the above mentioned energy range.

The CLIC Test Facility (CTF3) will demonstrate the generation of the drive beam with the appropriate time structure, the extraction of 30 GHz RF power from the beam and the acceleration of a probe beam. The INFN participation to the project is focused on the frequency multiplication system composed by special rings in which the bunch trains are combined.

In the talk the CTF3 project is described with special emphasis on the INFN contribution and the recent results on the first part of the commissioning.
