EURATOM contributions to the ITER Project include plasma and first wall diagnostics providing around a quarter of the primary measurements needed to avoid damage, to control the plasma and to explore its physics. These contributions include eight diagnostic systems, as well as six port plugs (housing a variety of diagnostics and other ITER systems) and extensive in-vessel electrical systems, providing connections to in-vessel diagnostics. The design phase for these systems is close to completion, and many are already in manufacture. This paper summarises the designs developed, and highlights the challenges addressed.
