Source of Low Emittance Muons for Future Collider
This project aims to develop a novel method to produce low emittance muon beams for a future muon collider by using a high-energy acceptance positron beam to generate muon pairs. Key research areas include positron ring studies, production target evaluations, collider background assessments, and performance comparisons. The project is structured into five work packages led by various researchers focusing on different aspects of the process.
