Are coated films candidate for ITER's first mirrors?

Metallic mirrors are foreseen to play a crucial role for all optical diagnostics of next generation of fusion reactor. Therefore, the development of reliable techniques for the production of mirrors that are able to maintain their optical properties in the harsh ITER environment is highly important. By applying magnetron sputtering and evaporation techniques, rhodium and molybdenum coated mirrors have been prepared for optical characterizations. These mirrors were exposed to deuterium plasma under erosion condition in laboratories and in tokamaks. The films were characterized in terms of chemical composition, surface roughness, crystallite structure, nanohardness and reflectivity.
