Patent ID: 7560687

Claim:
A polarized neutron guide capable of separating and transferring spin-up polarized neutrons and spin-down polarized neutrons from neutrons, the polarized neutron guide comprising: a body having a vacuum space formed therein through which neutrons are transferred, and including super mirrors disposed on a plane facing the vacuum space and coated with a neutron-reflective thin film; first and second spaces formed inside the body by the vacuum space partitioned by a first plate whose surfaces are coated with neutron-reflective thin films; and a neutron separation space formed by a second plate disposed at an entry of the first space, sloped to a front edge side of the first plate from an inner plane on one side of the body, and a third plate disposed at an entry of the second space, sloped to a front edge side of the first plate from an inner plane on the other side of the body, whereby spin-up polarized neutrons and spin-down polarized neutrons are simultaneously separated and transferred to the first and second spaces, respectively.
