Mosaic Crystals for Neutron Monochromators

Starting from high-quality single crystals, the ILL Neutron optics laboratory produces copper and germanium crystals with controlled mosaic spread for the construction of double-focusing neutron monochromators. ILL also produces Heusler single crystals with controlled mosaic for polarised neutrons.
