One of the options is the use of diagnostics based on Hall sensors that are well established in experimental physics and industry, although it is rarely implemented in the fusion plasma physics due to short pulse operation of majority of present day tokamaks. There are two main issues associated with the use of Hall sensors in harsh environment of future fusion reactors i.e. low survival temperature of presently available commercial transducers and questionable stability of these mostly semiconductor sensors under neutron irradiation. Hall sensors based on InSb thin film layers are presently being evaluated as one of the perspective options for ITER ex-vessel steady state magnetic sensors. Here, the compatibility with vacuum vessel baking temperature of 220 oC and with the peak life time neutron fluence of 1018 n/ Workplace Institute of Plasma Physics Contact Vladimíra Kebza, kebza@ipp.cas.cz, Tel.: 266 052 975 Year of Publishing 2010
