THE FEASIBILITY STUDY FOR THE FUTURE CIRCULAR COLLIDER (FCC) ENVISAGES THE CREATION OF A NEW RESEARCH INFRASTRUCTURE, WHICH COULD HOST DIFFERENT PARTICLE ACCELERATORS WITH A RESEARCH PROGRAMME EXTENDING UNTIL THE END OF THE 21st CENTURY.
If the study is conclusive and if the project is approved by CERN’s Member States, the civil engineering work could start around the mid 2030s. The central component of this project is a new tunnel with a circumference of approximately 92 km, extending over the Franco-Geneva basin. The first step would be the construction of a circular electron-positron collider, a veritable Higgs factory, which would provide very high-precision measurements allowing all the known particles of the Standard Model to be studied in detail.
