    A technology developed for creating radiationresistant magnetic field sensors based on semiconductor binary compounds of III-V group (InSb, InAs, GaAs) and their solid solutions (InXGa1-XAs, InAsXIn1-X) is presented. Studies have confirmed such sensors’ operability in neutron fluxes up to high fluences. This has made possible their use in magnetic measuring instrumentation for magnetic field diagnostics in thermonuclear reactors. The instrumentation comprises a 3D probe with Hall sensors and electronics characterized by the function of in-situ self-calibration, which makes available periodic calibration of sensors without their reinstallation, leading to high measurement accuracy. The magnetic measuring instrumentation developed by the team has been applied in European reactors TORE SUPRA (France) and JET (UK), and is aimed at solving tasks at a new charged particle accelerator – collider NICA (Russia).
