  • Publication number: 20250236454
    Abstract: An electrical control box for superconducting magnet transportation and a device for transporting a superconducting magnet, relating to the field of superconducting magnet transportation, are configured to transport the cryogenic superconducting magnet. The electrical control box for superconducting magnet transportation is provided to address the problem that rated load capacity requirement of the transport apparatus is too high while transporting the superconducting magnet. A function of one input to two outputs is implemented through a power supply distribution module to supply power to a helium compressor and a refrigerator respectively to align with the common practice of transport personnel. In addition, a delay module is arranged in a power supply output connected to the helium compressor to provide power to the helium compressor later than the refrigerator, i.e., the start-up of helium compressor and the refrigerator are asynchronous.

  • Patent number: 9588198
    Abstract: An open type nuclear magnetic resonance magnet system having an iron ring member. A superconducting coil and a superconducting switch form a closed-loop current circuit to generate a magnetic field. The generated magnetic field gains a magnetic flux circuit and executes magnetic field shielding through upper and lower iron yokes and a lateral iron yoke. The magnet system generates a desired magnetic field in a magnet imaging central area via the superconducting coil. To balance the extremely high electromagnetic force between the superconducting coil and the upper and lower iron yokes, an annular iron ring is mounted in a space defined by an inner perimeter wall of in a cryogenic container. The magnetic field distribution between the superconducting coil and the upper and lower iron yokes is changed via the iron ring, so that the electromagnetic interaction force therebetween is reduced.

  • Patent number: 8996083
    Abstract: A self-shield open magnetic resonance imaging superconducting magnet comprises five pairs of coils: shim coils, first main magnetic coils, second main magnetic coils, third main magnetic coils, and shielding coils. The five pairs of coils are symmetric about the center. The shim coils are arranged closest to the center point; the first main magnetic coils, the second main magnetic coils, the third main magnetic coils, and the shielding coils are arranged in sequence outside. The first main magnetic coils are connected with reverse current. The second and third main magnetic coils are connected with positive current for providing the main magnetic field strength. The shim coils are connected with positive current for compensating the magnetic field in the central region. The shielding coils are connected with reverse current for creating a magnetic field opposite to the main magnetic field for compensating the stray magnetic field in the space.
