Outline of Final Research Achievements

The new experimental technique for time-resolved pulsed neutron diffraction was developed by combining with high intensity neutron beam of J-PARC MLF and event recording system for neutron data and external field data. This technique makes it possible to evaluate the structure of materials under the cyclic external field with relatively high frequency through neutron scattering measurements. The response of the structural properties of the piezoelectric material in the piezoelectric actuator in operation was studied by this technique. The structural variation which is the origin of the motion of the actuator was successfully observed with millisecond time resolution.
