The public consultation process for the CERN-led Future Circular Collider (FCC) project will soon begin in Switzerland and France. These four months of exchanges and dialogue with the public are part of the preparations for a final decision on the project. As the CERN Council, comprising representatives of all the Organization’s Member States, prepares to update the European Strategy for Particle Physics on the basis of recommendations from the scientific community, the FCC remains a project under study for the time being, with the approval decision set to be taken in 2028 at the earliest.
If approved, the FCC would be installed in a ring-shaped underground tunnel measuring 91 km in circumference, at an average depth of 200 m beneath the Haute-Savoie and Ain departments in France and the canton of Geneva in Switzerland. It would collide electrons with their antiparticles, positrons, delivering results with an unprecedented level of precision and thus allowing the greatest mysteries of the Universe to be explored, as well as fostering innovation and the development of new technologies and skills in the coming decades.
