| Research Abstract |
Neutron interferometer has the advantage for fundamental physics experiments, for example, precision measurement of Aharonov-Chaser effect. It is important that high precision measurements using intense pulsed neutrons. We developed optical devices applicable to pulsed neutrons. Clear interference fringes were observed using time-of-flight method at beam line BL05 in J-PARC MLF.
Neutron spin echo (NSE) spectrometer is one of the techniques for quasi-elastic scattering with the highest energy resolution. We developed high frequency resonance spin flippers for pulsed neutrons. Intensity modulated spin echo signals, which are called as MIEZE signals, were observed according to the time-of-flight at beam line BL05 in J-PARC MLF. We plan to construct the spectrometers for practical use at J-PARC. We are also developing the compact devices for spin echo option for various spectrometers.
