Monochromators

 

The monochromator is the first and most important optical component of most ILL instruments.

While many cold-neutron instruments use pyrolytic graphite which is commercially available with a controlled mosaic, monochromators and analysers for thermal and hot neutrons have had to be developed and produced in-house.

 

The ILL has acquired world-leading skills in the production of large copper and Heusler alloy crystals with controlled mosaic.

We also modify home-grown and commercially available germanium crystals to obtain specific values of curvature and mosaic.
