| Outline of Final Research Achievements |
The precise measurements of muon anomalous magnetic moment (g-2) and electric dipole moment(EDM) investigate the existence of new physics. In order to fundamentally solve the systematic error factors of experiments that have been followed for nearly the past 30 years, we are promoting new experiment. One of major essences of the new experiment is the establishment of a method to control the beam into the compact storage ring with a radius of 33 cm. We inject a beam of momentum of 300 MeV / c into the storage ring of magnetic field strength 3 T adjusted by sub ppm. In this research project, we conducted a test beam line construction and a verification experiment demonstrating a three dimensional beam injection method to a newly invented solenoid type accumulating magnet. By adjusting the X - Y coupling that controls the horizontal and vertical motion of the beam, we can demonstrate the beam control technique in the small storage ring.
