“…A first assumption is that local impurities or physical changes at very small scales (of the order of few millimetres or below) are the most probable causes of TIEMF. This has been validated by all the experimental results obtained so far [7][8]. The second one is that the underlying physical cause is a local change of the Seebeck coefficient.…”

“…Work done in recent years has clearly demonstrated that radiation and temperature induced voltages (RIEMF and TIEMF, respectively) appear in all the cables studied so far (MI coaxial cables, ceramic and enamel coated single cables) [1][2][3][4][5][6][7][8]. TIEMF appears as generation of a voltage along the centre conductor of cables due to temperature gradients, (particularly large for MI Cu cored cables) and cable inhomogeneity.…”

ITER has diagnostics with machine protection, basic and advanced control, and physics roles. Several are distributed on the inner and outer periphery of the vacuum vessel. They have reduced maintainability compared to diagnostics in ports. They also endure some of the highest nuclear and EM loads of any diagnostic for the longest time. They include:Inductive sensors for time-integrated and raw inductive measurements; Steady-state magnetic sensors to correct drifts of the inductive sensors;Bolometer cameras to provide electromagnetic radiation tomography; Microfission chambers and neutron activation stations to provide fusion power and fluence; MM-wave reflectometry to measure the plasma density profile and the plasma-wall distance and;Wiring to service magnetics, bolometry, and in-vessel instrumentation. This paper summarises the key technological issues these diagnostics arising from the nuclear environment, recent progress and outstanding R&D for each system.
