Axisymmetric Grazing-Incidence Focusing Optics for Small-Angle Neutron Scattering
Atom and neutron optics X-ray optics small-angle neutron scattering
2012/5/17
We propose and design novel axisymmetric focusing mirrors, known as Wolter optics, for small-angle neutron scattering instruments. Ray-tracing simulations show that using the mirrors can result in mor...

SPHERES (SPectrometer with High Energy RESolution) is a third-generation neutron backscattering spectrometer, located at the 20 MW German neutron source FRM II and operated by the Juelich Centre for N...
From x-ray telescopes to neutron scattering: using axisymmetric mirrors to focus a neutron beam

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...
