摘要:
We describe novel, compact optical elements for collimating and/or focusing beams of slow neutrons. These optical elements are solid composites consisting of regular stacks of alternating micro-foils analogous in action to Soller slits. They are made out of pairs of metals with suitable refractive indices for reflection and/or absorption of the radiation. The performance of these proof-in-principle collimating elements is limited only by the choice of microfoil materials and uniformity of their interfaces.
