Muon Collider studies

Description of the project Muon colliders have a great potential for high-energy physics. They can offer collisions of point-like particles at very high energies, since muons can be accelerated in a ring without limitation from synchrotron radiation. However, the need for high Luminosity faces technical challenges which arise from the short muon lifetime at rest and difficulty of producing large numbers of muons bunches with small emittance. Addressing these challenges requires the development of innovative concepts and demanding technologies.

SCE contribution

The civil engineering team is leading the feasibility studies for the placement of the muon collider and the accelerator tunnels within the CERN region. To do so, the FS CE team is working together with the GIS team in the SCE department to develop a GIS based tool with bespoke functionalities to find the optimum layout and placement of the tunnels taking into account both underground and surface constraints. 

Muon Collider Test Facility Civil Engineering (CE) studies

A beam test facility is key to demonstrate items of critical importance to achieve the required luminosity in the Muon Collider, namely, 6D cooling, the integrated engineering of the cooling cells. 

The Future Studies section is leading the feasibility studies for the placement of such facility at CERN. Their main objective is to deliver a conceptual design with the associated CE cost and schedule estimates at the end of 2022. As a first option, the CE team is looking at the possibility to implement the Test Facility around the existing TT10, a transfer line to SPS from which a new beamline would be extracted.
