Times Cited Count：167 Percentile：99.33(Physics, Multidisciplinary)This paper introduces a new approach to measure the muon magnetic moment anomaly 
and the muon electric dipole moment (EDM) 
at the J-PARC muon facility. The goal of our experiment is to measure 
and using an independent method with a factor of 10 lower muon momentum, and a factor of 20 smaller diameter storage-ring solenoid compared with previous and ongoing muon g-2 experiments with unprecedented quality of the storage magnetic field. Additional significant differences from the present experimental method include a factor of 1000 smaller transverse emittance of the muon beam (reaccelerated thermal muon beam), its efficient vertical injection into the solenoid, and tracking each decay positron from muon decay to obtain its momentum vector. The precision goal for is a statistical uncertainty of 450 parts per billion (ppb), similar to the present experimental uncertainty, and a systematic uncertainty less than 70 ppb. The goal for EDM is a sensitivity of

In such a device an electromagnetic sensor that has a signal integrator to measure direct currents will cause a technical problem of zero point drift on signals. So, the detection device using new technology for direct current measurement, optical current transformer (optical CT), was developed. The device has an optical fiber specified for 1550nm (wavelength) was manufactured, and was applied to JT-60U experiments. A gamma ray irradiation examination was also done to the optical CT

In a nuclear fusion equipment device, plasma discharges are expected to become a long time. In such a device an electromagnetic sensor that has a signal integrator to measure direct currents will cause a technical problem of zero point drift on signals. Furthermore, the development for solving the problem cause cost rise. Therefore, the detection device using new technology for direct current measurement, optical fiber current transformer (optical CT), was developed. Direct-current measurement of JT-60 was carried out using this detection device. A 
ray irradiation examination was also done to the optical CT.

The ITER vacuum vessel (VV) R&D has progressed with the international collaborative efforts by the Japan, Russia and US Parties during the Engineering Design Activities (EDA). Fabrication and testing of a full-scale VV sector model and a port extension have yielded critical information on the fabrication and assembly technologies of the vacuum vessel, magnitude of welding distortions, dimensional accuracy and achievable tolerances during sector fabrication and field assembly. In particular, the dimensional tolerances of 
3 mm for VV sector fabrication and 10 mm for VV sector field assembly have been achieved and satisfied the requirements of 5 mm and 20 mm, respectively. Also, the basic feasibility of the remote welding robot has been demonstrated. This report presents detailed fabrication and assembly technologies such as welding technology applicable to the thick wall without large distortion, field joint welding technology between sectors and remote welding technology through the VV R&D project.

The MuSEUM experiment at J-PARC requires a long-term stability of less than 0.2 ppm time variation of magnetic field and less than 0.2 ppm (p-p) homogeneity for the ellipsoidal region of 20 cm in diameter and 30 cm in length. The superconducting magnet used in the MuSEUM experiment takes a method of shimming to adjust homogeneity by placing iron shims. The factors changing magnetic field with temperature is considered the location shift of shims due to the thermal expansion of the shimming structures and the temperature dependence of iron magnetization. Therefore, the magnetic field was measured during heating the shimming structure, and the temperature dependence of magnetic field was confirmed. In addition, location-shift and magnetization change were calculated by simulation. Based on the measurement and simulation results, it is necessary to control the room temperature within 0.2 K to keep long-term stability in the current experimental system.
