From x-ray telescopes to neutron scattering: using axisymmetric mirrors to focus a neutron beam
atom and neutron optics x-ray optics Instrumentation and Detectors
2012/4/24
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...
