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.
Optimised system designs for power efficiency, high efficiency klystrons, permanent magnets, renewable power… The linear collider projects are working to address power efficiency and reduce the environmental impact of the facilities.
In order to reduce the beam emittance by a large factor, the CLIC Collaboration has developed an innovative dipole magnet prototype and built a permanent magnet demonstrator
Set to finish at the end of year, the EU-funded CompactLight project held the promise of designing more compact and cost-effective linac-based photon sources.
Last February, the Compact Linear Collider (CLIC) team working on technical developments organised a workshop on all the different technologies developed for producing, handling, and preserving nanobeams and ultra-short bunches.
Stray magnetic fields are a serious consideration in the design CLIC. Measurements to characterise stray magnetic fields at CERN are presented and a mitigation technique for CLIC is discussed.
