| Outline of Final Research Achievements |
A method of spacial and time calibrations for the precise measurement of muon g-2/EDM was developed. A long-term stability of the reference frequency was realized by a GPS-aided Rb-atomic frequency standard with a synchronization to the national standard of frequency at NMIJ/AIST. Stability of the frequency was confirmed over long-term operation of more than 1 year. A new spacial alignment monitor was developed to monitor the position and orientation of the detector. A proof of principle tests were carried out with a laser interferometry constructed with an optical frequency comb. As a result of the test, the basic principle of the method was proven to work with a stability of the distance measurement better than 1 micro-meter.
