SUPERCONDUCTING MAGNET WITH CRYOGENIC THERMAL BUFFER Russian patent published in 2019 - IPC H01F6/04 

FIELD: electrical engineering.

SUBSTANCE: superconducting magnet device (14; 46) includes at least one coil winding (16₁-16₄) from superconducting wire to generate static magnetic field B₀, which is configured to establish a heat-conducting contact with cryogenic cooler (38) cold head designed to maintain, at least one coil winding (16₁-16₄) at temperature below critical temperature, at least one gas-proof container (40; 48), which continuously contains some amount of helium and is in heat-conducting contact with, at least, one coil winding (16₁-16₄) to absorb its heat energy in at least one operating condition. Magnetic resonance tomography system (10) is intended for producing magnetic resonance images, at least, from part of object (22) of interest containing such device (14; 46) of superconducting magnet, for generation of static magnetic field B₀ in analyzed space (20) of system (10) of magnetic resonance tomography.

EFFECT: technical result consists in improvement of thermal buffering at cryogenic temperatures.
