Materials issues in the Fusion Engineering Device

The design configuration and parameters of FED are described and several key design issues involving materials-related problems for components including armor, the pumped limiter, TF coils and various electrical systems, are briefly reviewed. The selected materials applications discussed illustrate design constraints arising from concerns about plasma-materials interactions, cyclic operation and neutron radiation damage. Materials testing in FED is also discussed with emphasis on a broad view of the role of FED in materials development
