During the execution of research design was developed planar and axial probes for mapping magnetic fields in terms of fusion reactors, particle accelerators, and space satelites. Developed technical documentation. Developed and implemented methods for precision positioning sensors and structural elements of magneto-measuring probes using optical laser technology. Developed and implemented methods for improving the accuracy of measurement of the magnetic field by reducing parasitic sensor signals caused by planar effects and off-set voltage. The research sensor signals in high magnetic fields up-to 14 T and at low temperatures 4,2 K in Laboratory of high magnetic fields and low temperatures (Wroclaw, Poland). The analysis of the impact of ionizing radiation on the radiation resistance of semiconductor materials and determining the physical basis of predicting properties of semiconductor materials exposed to radiation technology development modifications. The possibility of practical implementation of technology change settings indium-inclusive semiconductor material by controlled introduction of radiation defects. The cary out research and designed the technology of radiation modification heterostructure InSb / i-GaAs and InAs / i-GaAs, which provides stability parameters of Hall sensors based on them, in radiation conditions. The technology of radiation modification based on processes laid radiation sensors based on InSb and InAs certain reactor neutron spectrum. The defined technological modes of process modifications radiation sensors based on heterostructure InSb / i-GaAs and InAs / i-GaAs, namely: the optimal ratio of thermal and fast neutrons in the flow and optimum process temperature exposure. The cary out research a series of studies of radiation resistance of materials AIII BV and sensors based on them to high neutron fluence 1019n · cm-2 at the different energy spectra of neutrons in a reactor IBR-2 (JINR) and BD-m (PNPI). Developed and manufactured experimental models of magneto-measuring devices based on three-axis Hall probes, designed to work in a cryogenic temperatures and reactor neutron irradiation.5481 Product Description popup.authors Афанасьєв Д.М.
