dc.description.abstract | We demonstrate neutron beam focusing by axisymmetric mirror systems based on a pair of mirrors
consisting of a confocal ellipsoid and hyperboloid. Such a system, known as a Wolter mirror
configuration, is commonly used in x-ray telescopes. The axisymmetric Wolter geometry allows
nesting of several mirror pairs to increase collection efficiency. We have implemented a system
containing four nested Ni mirror pairs, which was tested by focusing a polychromatic neutron beam at
the MIT Reactor. In addition, we have carried out extensive ray-tracing simulations of the mirrors and
their performance in different situations. The major advantages of the Wolter mirrors are nesting for
large angular collection, and aberration-free performance. We discuss how these advantages can be
utilized to benefit various neutron scattering methods, such as imaging, SANS, and time-of-flight
spectroscopy. | en_US |
