An apparatus for controlling a neutron beam includes a plurality of columnar prismsthat are made of a material having a refractive index of less than 1 for a neutron beam, and are arranged so as to be multi-layered. The columnar prismseach have an approximately right-triangle-shaped section, and are three-dimensionally multi-layered such that respective surfacesof the columnar prisms are in parallel to one another. Stick-shaped membersare made of the above material, the stick-shaped membersare set in a plurality of grooves formed on a jigthat have the same shape, and upper surfaces of the grooves are flattened at the same time.

Apparatus for controlling neutron beam and method for manufacturing the same

A neutron beam controlling apparatus includes a plurality of multilayered plate members, each having on one or both of its surfaces, one or more minute protruding portions. Each of the protruding portions is a long and narrow protrusion extending in an area-wise direction and having both an inclined surface that is inclined against the beam axis of neutron beam and serves as an incident plane or an outgoing plane for the neutron beam and a surface approximately normal to the plate member.
