The development of beryllium single crystals for neutron monochromatization

Subgrain-free monocrystalline beryllium with the specific properties required for neutron monochromators are obtained by zone melting and subsequent deformation in order to increase the mosaic spread from a few minutes to any desired value. Neutron reflectivity measurements confirm the superiority o...

Description
Summary:Subgrain-free monocrystalline beryllium with the specific properties required for neutron monochromators are obtained by zone melting and subsequent deformation in order to increase the mosaic spread from a few minutes to any desired value. Neutron reflectivity measurements confirm the superiority of beryllium to all other monochromator materials for wavelengths smaller than 0.15 nm.
