European Strategy for Particle Physics

European Strategy for Particle Physics

The Compact Linear Collider (CLIC) is a TeV-scale high-luminosity linear electron-positron collider under development by international collaborations hosted by CERN.

For an optimal exploitation of its physics potential, CLIC is foreseen to be built and operated in stages, at centre-of-mass energies of 380 GeV, 1.5 TeV and 3 TeV, for a site length ranging between 11 km and 50 km. CLIC uses a two-beam acceleration scheme, in which normal-conducting high-gradient 12 GHz accelerating structures are powered via a high-current drive beam.

The construction of the first CLIC energy stage could start as early as 2026 and first beams would be available by 2035, marking the beginning of a physics programme spanning 25–30 years.

A number of documents report on the CLIC accelerator and detector and physics status in advance of the European Strategy update 2018-2020, including the design, technology, and implementation aspects of the CLIC accelerator and the detector, and summaries of the physics potential of CLIC.

The CLIC accelerator collaboration and CLIC Detector and Physics collaboration together comprise around 400 participants from approximately 75 institutes worldwide. Additional contributions are made from beyond the collaborations.
