The diffraction properties of a cylindrically bent, focusing copper crystal are discussed. Measurements with a γ‐diffractometer and a two‐axis diffractometer for thermal neutrons gave a means of checking the behaviour of the crystal. The monochromator reflects neutrons of a large range of wave‐vectors, between 5.5 and 6.8 Å −1 . The wavelength depends on the direction.
