| Outline of Final Research Achievements |
The flypast method was implemented in the D1 experimental area of J-PARC to improve the signal-to-noise ratio in pulsed muSR measurements. A muon beam trajectory was optimized for the flypast mode using a 3D muon beam profile monitor, which was developed for interactive tuning of a muon beam line. A long vacuum chamber, which plays a key role in the flypast mode, was optimally designed based on the observed beam trajectory. The signal-to-noise ratio in the optimal condition was estimated to be about 3 for a small sample with the cross-sectional area of φ4mm using a computer simulation code.
