Development of next generation muon beams at the Paul Scherrer Institute

Abstract

The Paul Scherrer Institute (PSI) provides the world's highest intensity muon beam of Ó(108)μ+/s at 28MeV/c. The HiMB project aims to improve this rate by two orders of magnitude. Meanwhile, the muCool collaboration is developing a device which converts a standard surface μ+ beam of cm-size and MeV-energy into a beam of 1mm-size and 1eV energy spread by achieving a compression of 6-dimensional phase space by 10 orders of magnitude with an efficiency of 10−3.
