Paper Abstract

Neutron mirror reflection is based on the phenomenon of total reflection of thermal neutrons discovered more than 40 years ago by Fermi and Zinn. Since Maier-Leibnitz and Springer's original proposal 30 years ago neutron mirror reflection has been widely used for beam channeling through guide tubes. Neutron mirrors are essential components for Doppler-shifting turbines as well as in high-resolution spectrometers for ultracold neutrons. We describe instrumentation making ample use of imaging mirrors for beam preparation and for neutron microscopy. The paper also reports a detailed analysis of specular and non-specular components in mirror reflection and transmission. Experimental reflection profiles are compared to those of zero-order diffraction from a planar ruled diffraction grating, and we scrutinise further "textbook experiments" testing the wave properties of neutrons.
