Compact Linear Collider (CLIC)

The Compact Linear Collider (CLIC) is a proposed accelerator, designed as an addition to CERN’s accelerator complex. Its objective is to collide electrons and positrons (antielectrons) head-on at energies of up to several teraelectronvolts (TeV). For an optimal exploitation of its physics potential, CLIC is intended to be built and operated in three stages, at collision energies of 380 GeV, 1.5 TeV and 3 TeV respectively, for a site length ranging from 11 to 50 km. The design and technology development for CLIC being is pursued by an international collaboration of more than 70 institutes in more than 30 countries.
