Description
We report about novel neutron interferometer using pulsed neutrons. In the case of conventional interferometer, crystal diffraction is used for splitting and superposition of neutron wave. The sensitivity of the interferometer has limitation in applicable wavelength. In addition, we must scan the phase shifter plate to get interferogram. This scanning creates the systematic uncertainty for long time measurement. We developed the neutron interferometer with multilayer mirrors which can use long wavelengths neutrons. It can be applied pulse neutron beam by using Time-Of-Flight method. Using pulsed neutrons, we can get interferogram along wavelength simultaneously without the phase shifter and suppress the environmental disturbance depending on time. I will report on the current activities of NI at J-PARC.
