Název v původním jazyce

Investigation of stability of ITER candidate Hall sensors under neutron irradiation

Popis výsledku v původním jazyce

Hall sensors offer an attractive true noninductive method of magnetic field measurements for fusion reactors. Their use for steady state magnetic diagnostics of ITER is presently limited by their questionable radiation and thermal stability. Issues of stable and reliable operation in ITER like radiation and thermal environment are addressed by the contribution. Recently, novel Hall sensors, compatible with temperatures up to 200 degC, were developed and their radiation stability was tested at LVR-15 reactor. Overview of the experimental set-up on LVR-15 reactor is given. Degradation of the sensor's sensitivity by several tens of percents was observed after neutron irradiation by the total neutron fluence of 2x1017 n/cm2. This level of neutron fluence is comparable to that expected to occur over the whole ITER life time for a sensor location just outside the ITER vessel. The in-situ recalibration techniques are expected to handle the observed degree of Hall sensors performance.
