Future Circular Collider is a proposed next-generation particle accelerator intended as a successor to the Large Hadron Collider and a cornerstone project envisaged by the European Organization for Nuclear Research to advance high-energy physics. The proposal aims to assemble a global collaboration involving laboratories such as Fermilab, SLAC National Accelerator Laboratory, KEK, and institutes from CERN member states and partner countries to probe phenomena beyond the Standard Model (physics). The project has motivated feasibility studies among national agencies including the European Commission, national funding bodies like the UK Research and Innovation, and advisory panels such as the European Strategy for Particle Physics.
Overview
The project builds on heritage from the Large Hadron Collider machine, the Large Electron–Positron Collider, and technology developments at facilities like DESY, Brookhaven National Laboratory, and Lawrence Berkeley National Laboratory. Its goal is to enable experimental programs comparable to historic programs at the Tevatron, Super Proton Synchrotron, and the Relativistic Heavy Ion Collider. Planning studies have drawn expertise from accelerator programs at IHEP (China), TRIUMF, and INFN institutions, and have considered lessons from international mega-projects such as the International Thermonuclear Experimental Reactor and the Square Kilometre Array. The conceptual effort included contributions from universities including University of Oxford, Massachusetts Institute of Technology, Harvard University, University of Tokyo, and University of California, Berkeley.
Design and Technical Specifications
Design concepts center on a superconducting magnet lattice extending to a circumference on the order of 80–100 km, leveraging high-field magnets under study at CERN and developed in collaboration with industry partners and laboratories such as Siemens, Toshiba, Mitsubishi Heavy Industries, Alstom, and research centers like CEA (France), KIT (Germany), and Paul Scherrer Institute. Magnet technology R&D references work at National High Magnetic Field Laboratory, ITER magnet development, and superconducting material research at Brookhaven National Laboratory and Argonne National Laboratory. Accelerator components build on radio-frequency developments at Cockcroft Institute, RAL, KEK RF, and timing systems refined at LCLS and XFEL (European XFEL). Detector concepts borrow from design teams behind ATLAS, CMS, ALICE, and LHCb, with sensor R&D informed by efforts at CERN EP, MAMI, and SLAC. Infrastructure studies incorporated civil designs similar to Channel Tunnel and Gotthard Base Tunnel engineering undertaken by firms like Strabag and Vinci, and geotechnical surveying methods used in projects at Geneva Airport.
Physics Goals and Research Program
Primary objectives include precision studies of the Higgs boson profile first observed by the ATLAS and CMS collaborations, searches for supersymmetry inspired by theories explored by researchers such as Steven Weinberg and Murray Gell-Mann, investigations of dark matter candidates associated with work by Vera Rubin and Fritz Zwicky, and exploration of electroweak symmetry breaking mechanisms developed in the literature of Peter Higgs and François Englert. The program would target rare processes analogous to those measured at the Belle II experiment, flavor physics complementary to LHCb and BaBar, and heavy-ion studies relevant to results from RHIC and ALICE. The collider could test models proposed in papers by Edward Witten, Nima Arkani-Hamed, and Lisa Randall, and provide precision inputs for cosmology constraints used by teams working with Planck (spacecraft) and WMAP data.
Site, Infrastructure, and Civil Engineering
Site selection examined the Geneva basin and surrounding cantons involving coordination with authorities such as the Canton of Geneva, the Confederation of Switzerland, and regional governments in neighboring France. Civil engineering plans considered tunneling precedents from the Alpine tunnels and methods used by contractors on the Gotthard Base Tunnel and the Mont Blanc Tunnel. Surface infrastructure planning addressed proximity to academic hubs like University of Geneva, École Polytechnique Fédérale de Lausanne, and industrial partners in the Rhône Valley. Utilities, transport, and environmental permitting drew on experience from projects overseen by agencies such as the European Commission and national bodies including French Ministry of Ecology and Swiss Federal Office for the Environment.
Cost, Timeline, and Governance
Cost estimates have been compared with large-scale science projects like the International Space Station, ITER, and the James Webb Space Telescope, with budgetary review processes similar to those conducted by the European Strategy Group and national science funding agencies including Deutsche Forschungsgemeinschaft and National Science Foundation. Governance models propose an international treaty framework involving signatories comparable to bodies that governed the CERN convention and cooperative arrangements modeled on the European Space Agency. Timeline scenarios forecast staged construction akin to programs at LEP and LHC with commissioning phases benchmarked against facilities such as XFEL and SuperKEKB.
Environmental and Safety Considerations
Environmental impact assessments reference precedents set during construction of facilities like Geneva Airport expansion and research installations at CERN Meyrin site, and safety frameworks borrow from standards used by International Atomic Energy Agency for non-nuclear facilities and occupational safety regimes observed at European Organisation for the Safety of Air Navigation. Radiation protection, cryogenics safety, and emergency planning incorporate best practices developed at Fermilab and industrial partners like Air Liquide and Linde. Biodiversity mitigation and water resource management mirror strategies used in large civil works coordinated with entities such as European Environment Agency and local conservation groups.
Reception, Criticism, and Alternatives
The proposal has prompted debate among stakeholders including the European Strategy Group, national academies such as the Royal Society, the Max Planck Society, and advisory committees like the US Particle Physics Project Prioritization Panel. Critics cite opportunity costs compared to investments in projects like neutrino experiments at DUNE, astroparticle observatories including Cherenkov Telescope Array, or accelerator alternatives proposed by groups at IHEP (China) and proponents of linear collider concepts such as the International Linear Collider and the Compact Linear Collider. Supporters point to potential transformative discoveries comparable to those enabled by CERN operations and historical breakthroughs credited to institutions like Cavendish Laboratory and Rutherford Appleton Laboratory.
