Relay Reflective Optics for Joint European Torus

Optical Surfaces Ltd. has received a sizeable order from the Culham Centre for Fusion Energy (CCFE) to manufacture the relay imaging reflective optics that will form part of two critical viewing diagnostic assemblies for the Joint European Torus (JET) when operating with a deuterium-tritium fuel mixture. The project is funded under the framework of EUROfusion.

Comprising a series of large diameter (up to 500mm) ultra-smooth flat and spherical mirrors, some of which will have a very long radius of curvature, the relay imaging reflective optics will allow CCFE to monitor a number of physical and operational parameters within the JET fusion vessel with remote cameras from behind the 3m thick concrete shield wall.
