![]() The project would also include boosting the existing LHC with new more powerful superconducting magnets. Enhancing the Large Hadron Collider to 27 TeV This machine could start operation in the late 2050s. The cost estimate for a superconducting proton machine that would afterwards use the same tunnel is around 15 billion euros. The physics programme could start by 2040 at the end of the High-Luminosity LHC. This collider would serve the worldwide physics community for 15 to 20 years. The cost of a large circular electron-positron collider would be in the 9-billion-euro range, including 5 billion euros for the civil engineering work for a 100-kilometer tunnel. These precise measurements would provide great sensitivity to possible tiny deviations from the Standard Model expectations, which would be a sign of new physics. ![]() Such a collider would be a very powerful “Higgs factory”, making it possible to detect new, rare processes and measure the known particles with precisions never achieved before. A large proton collider would present a leap forward in this exploration and decisively extend the physics programme beyond results provided by the LHC and a possible electron-positron collider.” said CERN Director for Research and Computing, Eckhard Elsen.Ī 90-to-365-GeV electron-positron machine with high luminosity could be a first step. “Proton colliders have been the tool-of-choice for generations to venture new physics at the smallest scale. In addition, it would also collide heavy ions, sustaining a rich heavy-ion physics programme to study the state of matter in the early universe. It would also allow us to access unprecedented energy scales, looking for new massive particles, with multiple opportunities for great discoveries. Reaching energies of 100 TeV and beyond would allow precise studies of how a Higgs particle interacts with another Higgs particle, and thorough exploration of the role of the electroweak-symmetry breaking in the history of our universe. Using new-generation high-field superconducting magnets, the FCC proton collider would offer a wide range of new physics opportunities. The FCC’s ultimate goal is to provide a 100-kilometer superconducting proton accelerator ring, with an energy of up to 100 TeV, meaning an order of magnitude more powerful than the LHC. ![]() It showcases the great physics opportunities offered by machines of unprecedented energy and intensity and describes the technical challenges, cost and schedule for realization. The Future Circular Collider (FCC) collaboration submitted its Conceptual Design Report (CDR) for publication, a four-volume document that presents the different options for a large circular collider of the future. ![]()
