Development and Testing of in-Vessel Equilibrium Pick-up Coils for ITER

A new concept of magnetic pick‐up coil has been developed, aimed at reducing radiation induced thermoelectric effects which could affect the quality of the signals of the magnetic diagnostic for ITER. A winding made of a ceramic‐coated conductor and impregnated with ceramic filler is proposed as an alternative to the Mineral Insulated Cable, presently indicated in ITER reference design. Some prototypes of the new in‐vessel pick‐up coils have been designed, built and tested, to assess the thermoelectric characteristics of the coils.
