MAGNETIC FIELD GENERATOR Russian patent published in 2021 - IPC H01F6/04 H01F6/06 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, to magnetic field generators using magnets based on second generation high-temperature superconducting tapes, and can find application in devices for whose operation a magnetic field is necessary, for example, in magnetic plasma rocket engines, plasma torches, devices for magnetic resonance imaging, cyclotrons for the production of medical isotopes, etc. The technical result is the improvement of performance by cooling to cryogenic temperatures without local overheating, leading to a loss of superconductivity. The generator contains a cryostat with pipes for the input and output of cryogenic liquid, at least one superconducting magnetic coil placed in the cryostat and connected to a voltage source by means of a superconducting cable, and a soldered connection of the superconducting cable with a superconducting magnetic coil. The cryostat is a sealed volume, bounded by walls in the form of internal and external cylinders and end walls connecting the internal and external cylinders. The longitudinal axis of the inner cylinder is displaced relative to the longitudinal axis of the outer cylinder and is parallel to this axis. The superconducting coil is located in the cryostat on the periphery of the inner cylinder. The solder joint is located in the part of the cryostat that is not occupied by the superconducting magnetic coil. The superconducting magnetic coil and the superconducting cable are made of second generation high-temperature superconducting tapes.

EFFECT: improvement of performance by cooling to cryogenic temperatures without local overheating leading to a loss of superconductivity.
