Neutron beam controlling apparatus, and neutron energy measuring apparatus

摘要

The invention discloses a neutron beam controlling apparatus comprising a plurality of multilayered plate members 11, in which each of the plate members 11 has on its one or both surfaces one or a plurality of minute protruding portions 12, in which each of the protruding portions 12 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. <IMAGE>
