| Research Abstract |
This research was aiming to improve a neutron scattering instrument and we have demonstrated innovative performances of a novel device, which was a crystal-analyzer. The principle of the instrument is called as the time-of-flight method, i. e., neutrons which is scattered by an experimental sample reflect by a crystal-analyzer and reach to a detector. The method demands preciseness of the arriving time. And also, spatial distribution of neutrons should be narrow. Therefore, we developed a novel design concept of the crystal-analyzer which simultaneously implements the time-focusing and the spatial-focusing. We have demonstrated its focusing performances by Monte-Carlo simulations and experiments.
