CERN Completes Feasibility Study for Next-Generation Particle Collider

The proposed 91-kilometer Future Circular Collider aims to deepen our understanding of the universe with unprecedented energy levels and precision.

The feasibility study for the Future Circular Collider (FCC), a successor to the Large Hadron Collider, confirms its technical viability and estimates a cost of $16-17 billion.
The FCC is planned to be built in two phases: an electron-positron collider in the 2040s and a proton-proton collider with 100 TeV collision energy in the 2070s.
The proposed collider would have a 91-kilometer circumference, significantly larger than the LHC's 27 kilometers, and operate at an average depth of 200 meters.
Environmental and socioeconomic considerations, including sustainable design and public engagement, were key components of the feasibility study.
The CERN Council will review the study in November 2025, with a final decision on the project’s approval expected in 2028.
