Welcome to the Compact Linear Collider Website

The Compact Linear Collider (CLIC) study is an international collaboration working on a concept for a machine to collide electrons and positrons (antielectrons) head-on at energies up to several Teraelectronvolts (TeV). This energy range is similar to the LHC’s, but using electrons and their antiparticles rather than protons, physicists will gain a different perspective on the underlying physics.

The aim is to use radiofrequency (RF) structures and a two-beam concept to produce accelerating fields as high as 100 MV per meter to reach a nominal total energy of 3 TeV, keeping the size and cost of the project within reach. An overview of the CLIC concept "in a nutshell" can be found here>>.

In a related project, the CLIC detector and physics collaboration is developing a detector to record collisions at the future high-energy Compact Linear Collider. Precision physics under challenging beam and background conditions is the key theme for the CLIC detector studies. This leads to a number of cutting-edge R&D activities within CLICdp.

CALIFES workshop took place at CERN

29/10/2016

It has been proposed to convert the 200 MeV S-band electron linac CALIFES, currently being part of the CTF3, into a new general stand alone electron beam facility at CERN. To establish the interest from users a three day workshop was held at CERN on October 10-12 2016. The workshop was a success; more than 90 participants from different laboratories and different research field came to present their ideas and wishes for how to use the CALIFES beam. Show more

Examples include beam instrumentation development, THz-research, impedance studies and high-gradient research, including novel technologies like dielectrics and plasmas. Many users expressed interest in commencing experiments as soon as possible. A workshop report is being prepared for the CERN management, who will take the final decision of establishing this test facility at CERN around the turn of the year. After a vote the name CLEAR - "CERN Linear Electron Accelerator for Research" - was proposed for the new test facility. See workshop pages >>
