Resistance of magnetic field sensors based on molybdenum nanofilms to intense neutron fluxes

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 molybdenu...

Description
Summary: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.
