Towards a muon collider

A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions at high luminosity and 10 TeV centre of mass energy are being investigated by the recently-formed International Muon Collider Collaboration. This Review summarises the status and the recent advances on muon colliders design, physics and detector studies. The aim is to provide a global perspective of the field and to outline directions for future work

Finales Kühlungszenario für einen Myon Collider - ein Türöffner für zukünfitge Entdeckungsmaschinen

Arbeit an der Bibliothek noch nicht eingelangt - Daten nicht geprüftAbweichender Titel nach Übersetzung der Verfasserin/des VerfassersDiscovering unknown phenomena in particle physics – one of the most essential aspects of high energy physics, requires optimizing and developing high energy particle accelerators, for new discoveries. To be able to reach high particle energies (TeV) at all, new accelerators are needed that are larger and come with high financial costs. For this reason, it is very relevant to develop energy efficient and economic accelerators while continuing progress in that area. One of the most important goals is not only produce Higgs bosons on a much larger scale than it is possible so far, but also generate completely unknown particles. This will allow us to determine the mass of these particles and is likely to give us a glimpse of the physics beyond the Standard Model and therefore opening new doors for groundbreaking discoveries. Since the publication of the European Strategy for Particle Physics in 2020, it is known that scientists are further working on creating a concept of a new muon accelerator led by CERN.Advantage of this technology include that muons are leptons and therefore convert the entire center of mass energy to create new particles during collisions, which would not be possible in collisions with hadrons. This makes the lepton accelerator to a precision and discovery machine at high energies. Further, muons are 200 times heavier than electrons. As a result, bremsstrahlung and synchotron radiation may be neglected, which in turn cannot be done with electron accelerations. Nevertheless, the muon beam creates a high emittance after its creation, which drives the divergence of the beam. The only feasible way to reduce or cool this emittance within the very short lifetime of the muon is based on the principle of ionization cooling. Past studies have not achieved optimal final emittance values. Therefore, this work aims at gradually cooling the emittance of the muons beam by means of specific absorbers inside very high magnetic fields before it is finally accelerated to several TeV. As a result, the final cooling system should provide muon beams with the optimal properties required by the muon collider design.10

Automated Design and Optimization of the Final Cooling for a Muon Collider

The desired beam emittance for a Muon collider is several orders of magnitude less than the one of the muon beams produced at the front-end target. Ionization cooling has been demonstrated as a suitable technique for the reduction of the muon beam emittance. Final cooling, as one of the most critical stages of the muon collider complex, necessitates careful design and optimization in order to control the beam dynamics and ensure efficient emittance reduction. We present an optimization framework based on ICool simulation code and application of different optimization algorithms, to automatize the choice of optimal initial muon beam parameters and simultaneous tuning of numerous final cooling components
