| Outline of Final Research Achievements |
A difference of more than three standard deviations exists between the Standard Model prediction and the measured value in muon anomalous magnetic moment (g-2). Because there has been no measurement for a decade of more, we are developing muon linear accelerator to realize new measurement with new scheme. The muon acceleration, however, had not been realized.
We completed following three developments: (1) Complete of the muon linac design to accelerate muon from 25 meV to 212 MeV: (2) Development of the muon beam profile monitor which is sensitive to low energy and single muon: (3) Demonstration of the muon linear acceleration, which is the first time in the world.
