	Low-energy muon beams are useful for rare decay researches, providing access to new physics that cannot be addressed at high-energy colliders. However, the large initial energy spread of the muon beam greatly limits the efficiency of muon applications. In this paper we outline a phase rotation method to significantly increase the intensity of low-energy muons. The muons are first produced by a short pulsed proton driver, and after a drift channel they form a time-momentum correlation. A series of rf cavities is used to bunch the muons and then phase rotate the bunches so that all the bunches reaches a momentum around 100 MeV/c. Then another group of rf cavities is used to decelerate the muon bunches to low-energy. Such a method produces low-energy muons with an efficiency of 0.1 muon per 8 GeV proton, which is significantly higher than the current Mu2e experiment at Fermilab, and it provides the possibility for the next generation rare decay researches.

Low-energy muon beams are useful for rare decay researches, providing access to new physics that cannot be addressed at high-energy colliders. However, the large initial energy spread of the muon beam greatly limits the efficiency of muon applications. In this paper we outline a phase rotation method to significantly increase the intensity of low-energy muons. The muons are first produced by a short pulsed proton driver, and after a drift channel they form a time-momentum correlation. A series of rf cavities is used to bunch the muons and then phase rotate the bunches so that all the bunches reaches a momentum around 100 MeV/c. Then another group of rf cavities is used to decelerate the muon bunches to low-energy. Such a method produces low-energy muons with an efficiency of 0.1 muon per 8 GeV proton, which is significantly higher than the current Mu2e experiment at Fermilab, and it provides the possibility for the next generation rare decay researches.
