CERN’s Ambitious Future Circular Collider Project Takes Major Step Forward

Lead: CERN, the European Organization for Nuclear Research located near Geneva, Switzerland, has made significant strides in its Future Circular Collider (FCC) project, which seeks to construct a particle accelerator three times the size of the existing Large Hadron Collider (LHC). On March 31, 2023, the organization published a detailed feasibility study projecting a cost of 15.32 billion Swiss francs (approximately $17.4 billion) for the initial phase of this ambitious project. The FCC aims to collide electrons and their antiparticles, known as positrons, by the mid-2040s, allowing for unprecedented insights into the Higgs boson and other fundamental particles. The CERN Council is expected to review this feasibility study in light of its long-term strategy, with crucial funding scenarios yet to be outlined.

Unveiling the Feasibility Study

The three-volume feasibility study represents the contributions of about 1,500 physicists and engineers who have collaborated to design a monumental project capable of redefining the field of particle physics. The study emphasizes the following key points:

• The FCC aims to be a 91-kilometer-long circular tunnel located underground.
• This project will allow detailed studies of particles, including the Higgs boson, at unprecedented precision.
• The initial construction phase could be completed by the mid-2040s.

Economic Insights and Cost Structure

As part of the FCC’s ambitious scope, the estimated cost breakdown includes:

• Initial construction: 15.32 billion Swiss francs (US$17.4 billion).
• Second stage involving proton collisions: projected cost of 18.8 billion Swiss francs.
• The second stage is not anticipated to begin before 2072.

Fabiola Gianotti, CERN’s director general, expressed optimism about the FCC’s potential impact. “If approved and implemented, the FCC could become the most extraordinary instrument ever built by humanity to study the laws of nature at the most fundamental level,” she stated during a presentation to reporters.

Future Phases of the FCC Project

The feasibility study outlines a two-phase plan, where the first phase focuses on electron-positron collisions. A subsequent phase would utilize the same tunnel to facilitate proton collisions, similar to the current operations of the LHC. This second phase is expected to enhance energy levels significantly:

• Estimated energy levels of 85 Tera-electronvolts (TeV) for the proton collider, significantly surpassing those of the LHC.
• Future advancements in superconducting materials may potentially raise energy levels to 120 TeV.

Industry Reactions and Endorsements

CERN Council President Konstantinos Fountas emphasized the importance of the study in guiding the Council’s decisions. He noted that the project would provide “very solid ground” for informed discussions regarding its future. Antonio Zoccoli, president of Italy’s National Institute of Nuclear Physics, echoed this sentiment, voicing confidence in the thoroughness of the technical design and cost assessment.

The Next Steps in the Decision-Making Process

While the FCC project’s feasibility study has marked a pivotal moment in its development, the decision-making process remains ongoing:

• The CERN Council is expected to review the findings and consider possible funding scenarios in the upcoming year.
• The eventual endorsement of the FCC project may depend on the ability to secure financial backing and political support from participating member states.

“This study is the result of an immense amount of work carried out by the international FCC collaboration,” Gianotti concluded, underscoring the study’s collaborative nature and significance.

The Impact of the Future Circular Collider

If the Future Circular Collider becomes a reality, it would profoundly impact various scientific domains, including:

• Understanding the fundamental forces and particles that make up our universe.
• Providing key insights into dark matter and energy, areas that remain deeply mysterious in modern astrophysics.
• Offering opportunities for unprecedented technological advances in fields such as superconductivity and particle detection.

Concluding Thoughts

The Future Circular Collider project, with its ambitious goals and robust feasibility study, represents a new frontier for particle physics research. As CERN prepares for critical decisions in the coming months, the global scientific community eagerly anticipates how this monumental project will shape our understanding of the universe. With its potential to unlock the mysteries of fundamental particles, the FCC stands poised to influence a generation of scientists and researchers for decades to come.
