R&D STATUS OF THE HIGH-INTENSE MONOCHROMATIC LOW-ENERGY MUON SOURCE : PRISM

PRISM is in the works to build a future intense lowenergy muon source, which combines monochromaticity and high purity. In the PRISM project, an FFAG is used as the phase rotator to achieve the monochromatic muon beams. This paper will describe the design status the project.
