CERN concludes feasibility study for 91-kilometer Future Circular Collider, confirming technical and environmental viability

The Future Circular Collider (FCC) feasibility study at CERN has concluded, detailing a specific, geolocalized territorial implementation scenario for a 91-kilometer underground ring in France and Switzerland. The study confirms that the proposed infrastructure is technically feasible and environmentally compatible, providing a foundation for formal authorization processes. This phased program aims to address major open questions in particle physics, with the FCC-ee (electron-positron collider) recommended as the preferred option for the next flagship collider.
