Key Results of the FCC Feasibility Study and Steps Towards Implementation

The proposed Future Circular Collider (FCC) integrated programme consists of two stages: An electron–positron collider serving as a highest-luminosity Higgs-boson, electroweak and top-quark factory, followed by a proton–proton collider with a collision energy around 100 TeV. In 2021, the CERN Council launched the FCC Feasibility Study. This study covered, inter alia, physics objectives and potential, geology, civil engineering, technical infrastructure, territorial implementation, environmental aspects, R&D needs for the accelerators and detectors, socio-economic benefits, and cost. The Feasibility Study was completed end of March 2025. The subsequent European Strategy Symposium in June 2025 has singled out the FCC as the preferred future collider option for CERN. This talk will focus on preparations for FCC implementation, infrastructure, and accelerator design.
