Device for a neutron beam regulation and apparatus for measurement of the neutron energy

摘要

PROBLEM TO BE SOLVED: To make it possible to control the form, speed and direction of a neutron beam. ;SOLUTION: Plate members 11 where one or a plurality minute protrusions 12 that give an incidence plane or an emission plane inclining to a neutron beam 16 are provided in their faces are stacked. Each of the minute protrusions 12 is shaped, for example, as a slender one that has an approximately vertical plane and an inclined plane to a plane of the plate members 11 and extends toward the inside of the plane (The sectional form of the slender protrusion that is perpendicular in the direction of its length is a triangle). Consequently, the beam distribution form, speed and direction of a neutron beam can be freely controlled. The energy of neutrons can also be measured easily and directly.;COPYRIGHT: (C)2000,JPO
