An international collaboration has published its concept design for a post-LHC future circular collider at CERN.

The Future Circular Collider (FCC) collaboration submitted a Conceptual Design Report (CDR) for publication. It is a four-volume document that presents the different options for a large circular collider of the future. According to CERN, this showcases the great physics opportunities offered by machines of unprecedented energy and intensity. It also describes the technical challenges, cost and schedule for realising the ambitious conceptual design.

The ambitious design

CERN Director for Accelerators and Technology, Frédérick Bordry, added: “The FCC’s ultimate goal is to provide a 100-km superconducting proton accelerator ring, with an energy of up to 100 TeV, meaning an order of magnitude more powerful than the LHC. The FCC timeline foresees starting with an electron-positron machine, just as LEP preceded the LHC. This would enable a rich programme to benefit the particle physics community throughout the twenty-first century.”

The impact of the future circular collider

The discovery of the Higgs boson particle at the LHC opened a new path for physics research. Detailed studies of its properties are a priority for future high-energy physics accelerators. The different options explored by the FCC study offer opportunities to study both the Higgs boson.

CERN Director-General Fabiola Gianotti, said: “The FCC conceptual design report is a remarkable accomplishment. It shows the tremendous potential of the FCC to improve our knowledge of fundamental physics and to advance many technologies with a broad impact on society. While presenting new, daunting challenges, the FCC would greatly benefit from CERN’s expertise, accelerator complex and infrastructures, which have been developed over more than half a century.”

CERN Director for Research and Computing, Eckhard Elsen, added: “Proton colliders have been the tool-of-choice for generations to venture new physics at the smallest scale. A large proton collider would present a leap forward in this exploration and decisively extend the physics programme beyond results provided by the LHC and a possible electron-positron collider.”
