Abstract: The conceptual and technological development of ITER divertor thermography approaches the aim to provide measurements for machine protection and physics studies even for the case of an eventual change to metallic targets. This requires not only the use of spectrally resolved imaging thermography but also the use of various additional calibration and precision measurement tools such as pyroreflectometry and the use of the photothermal effect. The question of the optical transport through the divertor port is resolved in a compromise with justification for both conventional and fibre elements. The remote handling sequence for such a device is demonstrated. The next steps to take are outlined. [Copyright &y& Elsevier]

Abstract: On the limiter of Tore Supra, the heat loads map computed from deconvolution of IR surface temperatures shows good agreement with calorimetry measurements. This experimental heat pattern allows deducing the heat fluxes in the scrape-off layer using a 3D magnetic calculation and assuming only parallel heat transport along field lines. This calculation leads to an underestimation of the power circulating in the edge plasma according to the power balance, similarly to RFA measurements. The comparison between experimental heat loads on the limiter and modelling also shows a spreading of heat fluxes near the LCFS that cannot be explained only by parallel transport in the SOL.
