During the ITER Conceptual Design Activity (CDA), overall design study of diagnostic systems for the next generation machine was performed for the first time. Three Workshops on Plasma Diagnostics were held. Starting from reviews of operating experience with diagnostics on currently operating devices and early concepts of the requirements for plasma measurements, a set of diagnostics for the full operation of ITER has been developed. This report summarizes the results of these design activities and design integration efforts in trying to accommodate these diagnostics into overall ITER concept. In addition, the principal tasks of Diagnostic R & D are also described.
