概要

• 論文の詳細を見る

• A wide band neutron monochromator consisting of a stack of four multilayers on two Si wafers has been developed. One multilayer has 201 Ni/Ti layers. The layer thickness is gradually changed in order to extend the neutron reflection wavelength range similar to a supermirror. Multilayers were fabricated by the vacuum evaporation methods on each side of a Si substrate of 225 μm in thickness. Neutron reflectivity was measured by the θ-2θ reflectometer using cold neutrons. The neutron reflection wavelength was broadened to 19–40 nm by this stack from 26–40 nm of one multilayer.
