    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.
