【 摘 要 】

Influence of the reactor neutrons fluxes on parameters of Hall sensors based on molybdenum nanofilms had been investigated experimentally in real-time operation (on-line mode). Sensors sensitivity remained stable up to fluence of 1•1024 n•m-2 at temperature ≈ 130 °C. It allows to recommend molybdenum sensors as the radiation-resistant magnetic diagnostic front-end components for fusion reactors type of ITER and DEMO.
