Abstract

For the neutron phase imaging with a Talbot-Lau interferometer, we have fabricated neutron absorption gratings with a pitch of 9 μm by oblique evaporation of gadolinium. The performances of these gratings for the phase measurement were experimentally evaluated at RADEN in J-PARC, by observing the neutron transmission and the visibility of moiré fringe in the interferometer. A new analysis method using the wavelength-resolved neutron transmission was also attempted to estimate the characteristics of gratings.
