Research abstract
Mosaic crystalline monochromators define performance of neutron scattering devices employed in condensed matter research on research nuclear reactors. This project is devoted to development of a manufacturing technique for slow neutron Germanium mosaic monochromators with reflectivity exceeding reflectivity of pyrolytic graphite crystals. Germanium has small slow neutron absorption; its diamond crystal structure has a many more crystallographic orientations useful for neutron and x-ray scattering than pyrolytic graphite and for many orientations second orders of reflections in Germanium are prohibited. The proposed manufacturing technique utilizes optimized high temperature plastic deformation of large single Germanium crystals to produce mosaic monochromators.
