International Muon Collider Collaboration Cooling Demonstrator Workshop

Europe/Zurich
Chris Rogers
Description

High-energy muon colliders combine cutting edge discovery potential with precision measurements. Because muons are point-like particles they can achieve comparable physics to protons at much lower centre-of-mass energies. Due to the muon’s high mass, synchrotron radiation production is suppressed compared to electrons. This makes a high energy muon collider an excellent candidate for discovery at the energy frontier. The International Muon Collider Collaboration (IMCC) is charged by CERN after the past 2020 ESPPU recommendation to deliver an assessment of the potential for a muon collider to be a future collider facility and to plan the required R&D to deliver such a facility. The IMCC is also supported by the EU MuCol design study project. The Particle Physics Project Prioritisation Panel has identified the muon collider as an important future possibility for the US particle physics community.

One of the key challenges in development of the muon collider is delivery of a high brightness muon beam, which is essential to produce sufficient luminosity. Ionisation cooling is the technique that is planned to increase beam brightness. The ionisation cooling technique has been demonstrated in principle by the Muon Ionisation Cooling Experiment. However, a number of questions remain that must be answered in order to prove that the technique can be applied in practice. The IMCC foresees a Muon Cooling Demonstrator and associated development programme that must be executed in order to deliver the muon collider.

Following previous workshops, The IMCC will host the next meeting on the Muon Cooling Demonstrator at the INFN an University of Milan from 5 November to 7 November 2025.

There will be an additional Cooling Simulation Working Workshop on 4 November for support in installing and running accelerator simulations of the Demonstrator lattice.
