Institut Laue-Langevin

We provide neutron optical components for optimising neutron instruments. From monochromator and analyser crystals to converging guides, bandpass filters and polarising 3He spin-filters and supermirror devices, the ILL neutron optics lab provides the know-how and the in-house manufacturing capabilities. We develop and produce the neutron optical components required to maintain the leading role of the ILL in neutron scattering.

Crystal Growth

Crystal Growth

Recent progress in the growth of large copper single crystals at ILL has resulted in the production of copper crystals with a very narrow and uniform mosaic spread in the range of 20 seconds to 1 arc-minute. We have also succeeded in growing high-quality germanium single crystals with a neutron mosaic spread of up to 0.1° and Heusler single crystals with a specific mosaic.
