Abstract

A new measurement of the anomalous magnetic moment of the positive muon a μ is proposed with a novel technique utilizing an ultra-cold muon beam accelerated to 300 MeV/ c and a 66 cm-diameter muon storage ring without focusing-electric field. This measurement will be complimentary to the previous measurement that achieved 0.54 ppm accuracy with the magic energy of 3.1 GeV in a 14 m diameter storage ring. The proposed experiment aims to achieve the sensitivity down to 0.1 ppm.
