Research abstract
This project is devoted to development of a manufacturing technique of slow neutron Germanium mosaic monochromators with reflectivity exceeding reflectivity of pyrolytic graphite crystals. The manufacturing technique utilizes optimized high temperature plastic deformation of large single Germanium crystals to produce mosaic monochromators. Preliminary test on 70 mm diameter Ge samples with 111 orientation and mosaicity value 16 arc minutes demonstrated maximum neutron reflectivity 89% in the peak of a smooth rocking curve.
