The Future Circular Collider (FCC) study aims at developing conceptual designs for a post-LHC particle accelerator research infrastructure in a global context, with an energy significantly above that of previous circular colliders (SPS, Tevatron, LHC).
The FCC study explores the feasibility of different particle collider scenarios with the aim of significantly expanding the current energy and luminosity frontiers. 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 in-depth 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 is planned to be delivered before the end of 2018, in time for the next update of the European Strategy for Particle Physics.
The study hosted by CERN has been initiated as a direct response to the high-priority recommendation of the updated European Strategy for Particle Physics, published in 2013:
"CERN should undertake design studies for accelerator projects in a global context, with emphasis on proton-proton and electron- positron high-energy frontier machines. These design studies should be coupled to a vigorous accelerator R&D programme, including high-field magnets and high-gradient accelerating structures, in collaboration with national institutes, laboratories and universities worldwide."
This is in line with the recommendations of the United States’ Particle Physics Project Prioritization Panel (P5) and of the International Committee for Future Accelerators ICFA).
The discovery of the Higgs boson at the LHC, together with the absence so far of any phenomena beyond the Standard Model in collisions at centre of mass energies up to 8 TeV, has triggered an interest in future colliders to push the energy and precision frontiers. A future “energy frontier” collider at 100 TeV is a “discovery machine”, reaching out to so far unknown territories. "New physics" seen at such a machine could explain observations such as the prevalence of matter over antimatter and non-zero neutrino masses.
