Sumário do Projecto

Two facility concepts have been considered in the past years as pathways to the future of particle physics at the energy frontier in Europe: FCC-hh, a 100 TeV circular hadron collider and CLIC, a 3 TeV linear lepton (i.e. electron-positron) collider. They are improved versions of projects realised in the past. The expected cost and power consumption are 24 GCHF and 580 MW for FCC-hh and 18 GCHF and 590 MW for CLIC.The recent European Accelerator R&D Roadmap (https://arxiv.org/abs/2201.07895) includes a 10 or more TeV Muon Collider. This novel interest is based on two considerations:- The recognition of the physics potential of a lepton collider with a centre-of-mass energy of 10 TeV or more.- The recent advances in technology that make the realisation of a muon collider plausible.The Muon collider promises to expand the lepton collider energy reach. Muons are much heavier than electrons and with a much reduced synchrotron radiation, allowing acceleration and collision of the beam in rings, even at multi-TeV energies. This results in compact dimensions and promises high efficiency and limited cost. The tunnel length of a 10 TeV muon collider is expected to be similar to the 3 TeV CLIC and significantly smaller than FCC-hh. Because muons are point-like particles, in contrast to the composite hadrons, a muon collider may have a physics case of comparable interest than a 100 TeV hadron collider.Past work has demonstrated several key muon collider technologies and concepts, and gives confidence that the facility concept is viable. Component designs have been developed that can cool the initially diffuse beam and accelerate it to multi-TeV energy on a time scale compatible with the muon lifetime. Relevant technologies, e.g. superconducting magnets, have recently progressed.While the muon collider promises high benefits it also poses a significant risk. No muon collider has yet been built. The facility is based on advanced concepts and technologies. The Roadmap identifies remaining key challenges that require to be addressed by the next ESPPU so that the High Energy Physics community may make informed choices.MuCol will address the core of these key challenges. It will develop the baseline design and assess the physics performance based on realistic performance goals for the collider components. The identification of the cost and power consumption drivers will enable determination of the cost and power consumption scale. This will allow the next European Strategy for Particle Physics Update (ESPPU) process to seriously consider also Muon Colliders for the selection of the next large collider to be built in Europe.
