New approach to the Muon g-2 and EDM experiment at J-PARC

Abstract

A new measurement of anomalous magnetic moment of the positive muon a μ down to the level of 0.01 ppm and the electric dipole moment EDM with the improved sensitivity better than order of magnitude is proposed. Novel techniques utilizing an ultra-cold muon beam accelerated to 300 MeV/c and a 66 cm diameter of super-precisely controlled magnetic storage ring are introduced. An unique beam injection and storage scheme to control the beam trajectory into such a compact storage ring are also discussed.
