Future Circular Collider

The Future Circular Collider (FCC) is a conceptual study that aims to develop designs for a post-LHC particle accelerator with an energy significantly above that of previous circular colliders (SPS, Tevatron, LHC). After injection at 3.3 TeV, each beam would have a total energy of 560 MJ. At collision energy of 100 TeV this increases to 16.7 GJ. These total energy values exceed the present LHC by nearly a factor of 30.

These total energy values exceed the present LHC by nearly a factor of 30. The FCC study explores the feasibility of different particle collider scenarios with the aim of significantly increasing the energy and luminosity compared to existing colliders. It aims to complement existing technical designs for linear electron/positron colliders (ILC and CLIC). The study has an emphasis on proton/proton (hadron) and electron/positron (lepton) colliders while a hadron/lepton scenario is also examined. The study explores the potential of hadron and lepton circular colliders, performing an analysis of infrastructure and operation concepts and considering the technology research and development programmes that are required to build and operate a future circular collider. A conceptual design report was published in early 2019, in time for the next update of the European Strategy for Particle Physics.
