Transverse Collective Effects studies for a Muon Collider

2025

Abstract

The International Muon Collider Collaboration (IMCC) is investigating the key challenges of a 10 TeV centre-of-mass muon collider ring, along with its injector complex and an intermediate 3 TeV collider stage. Muon and anti-muon bunches are produced via a proton driver complex and then undergo a process called 6D cooling. The bunches are then accelerated by a series of Linacs, Recirculating Linacs (RLA) and Rapid Cycling Synchrotrons (RCS) before entering the collider ring. Collective effects are a concern due to the high charge of the muon bunches. The RCS require a significant number of RF cavities to rapidly accelerate the beams and keep a 90 % survival rate in each ring. The effect of the cavity high-order modes (HOMs) was evaluated using start-to-end simulations that included collective effects. The collider would be an isochronous ring to preserve a short bunch length. The study also examined the impact of this operation on transverse coherent stability, and potential methods for mitigating instabilities.

Large Hadron Collider

The Large Hadron Collider (LHC) is the world's largest and highest-energy particle collider. It was built by the European Organization for Nuclear Research (CERN) between 1998 and 2008 in collaboration with over 10,000 scientists and hundreds of universities and laboratories, as well as more than 100 countries. It lies in a tunnel in circumference and as deep as beneath the France–Switzerland border near Geneva. The first collisions were achieved in 2010 at an energy of 3.

Collider

A collider is a type of particle accelerator that brings two opposing particle beams together such that the particles collide. Colliders may either be ring accelerators or linear accelerators. Colliders are used as a research tool in particle physics by accelerating particles to very high kinetic energy and letting them impact other particles. Analysis of the byproducts of these collisions gives scientists good evidence of the structure of the subatomic world and the laws of nature governing it.

Large Electron–Positron Collider

The Large Electron–Positron Collider (LEP) was one of the largest particle accelerators ever constructed. It was built at CERN, a multi-national centre for research in nuclear and particle physics near Geneva, Switzerland. LEP collided electrons with positrons at energies that reached 209 GeV. It was a circular collider with a circumference of 27 kilometres built in a tunnel roughly 100 m (300 ft) underground and passing through Switzerland and France. LEP was used from 1989 until 2000.
