Description

Technical Field

[0001] This utility model relates to the field of superconducting magnet assembly technology, and in particular to a superconducting magnet assembly positioning structure. Background Technology

[0002] Superconducting magnets are electromagnets made by using coils of type II superconductors with high transition temperatures and exceptionally high critical magnetic fields at low temperatures. Their main characteristics are the absence of electrical losses due to wire resistance and magnetic losses due to the presence of an iron core, making them highly practical and widely used in industry and scientific research.

[0003] Patent application CN220474478U discloses a superconducting magnet assembly and positioning structure. The device includes a vacuum chamber assembly, a cold shield assembly, and a winding assembly. A vacuum chamber fixing component is connected to the bottom of the vacuum chamber assembly. A cold shield tip is connected inside the vacuum chamber fixing component and is connected to the bottom of the cold shield assembly. A winding tip is connected inside the cold shield tip and penetrates through the bottom of the cold shield assembly, connecting to the bottom of the winding assembly. By detachably mounting the winding tip, cold shield tip, vacuum chamber fixing component, first positioning nut, and second positioning nut at the bottom of the vacuum chamber assembly, the superconducting magnet can be installed from bottom to top. This structure also ensures the concentricity of the winding assembly and the vacuum chamber assembly. After installation, the structure can be removed, and a blind plate and sealing ring are used to seal the pre-drilled hole at the bottom of the vacuum chamber assembly, preventing additional heat leakage.

[0004] In the aforementioned related technologies, it is inconvenient to position the winding components and to perform positioning operations with multiple sets of nuts when assembling superconducting magnets. To address these issues, we have introduced a superconducting magnet assembly and positioning structure. Utility Model Content
