Abstract

A neutron lens comprises a series of silicon wafers (2), each preferably shaped to describe a two dimensional ellipsoidal surface, with a neutron reflecting coating (4) sandwiched between adjacent wafers. The wafers are arranged so that their major axes are approximately aligned with the neutron beam direction. The wafers of silicon act as conduits for the neutrons and also provide structural surfaces to which the neutron reflecting coating (4) is applied. With the neutron lens the gauge volume can be defined with a higher flux of neutrons than has previously been possible.
