Popis: The preparation of intercalated graphite compounds is now well established at the Institut Laue Langevin (ILL). We are able to manufacture several types of intercalated crystals, such as KC 8, RbC 8 , KC 24 and RbC 24 compounds, in large quantities and in a reproducible manner. Even though the mosaic distribution is large, these compounds exhibit a high neutron peak reflectivity of about 70% at a neutron wavelength of 9.8 A. The production of such intercalated graphite crystals allows us to build efficient neutron monochromators for wavelengths in the range 6–15 A.
