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.
