This contribution reviews the performance requirements and radiation-induced degradation mechanisms of functional materials intended for operation in fusion reactors, including optical elements, electrical insulators and materials used in sensing systems. Building on the activities of the EUROfusion Functional Materials group, we identify the key irradiation needs for future fusion devices and assess how they could be addressed by IFMIF-DONES.
Particular attention is given to extending irradiation experiments from bulk materials to functional elements, interfaces and small instrumented mock-ups. This is essential for validating magnetic and optical sensors, diagnostic components, and heating and control systems, whose performance also depends on cables, optical fibres and feedthroughs.
Finally, we discuss the experimental interfaces that may be required in the DONES irradiation area for the future qualification of functional components and integrated sensor systems
