Research Progresses Concerning the Superconducting Joints Used in Nuclear Magnetic Resonance Magnets

Highly stable magnetic field is essential to nuclear magnetic resonance (NMR) spectrometers. To maintain the magnetic field stability, high-quality superconducting joints are required. Along with the development of NMR superconductor magnet, researches on superconducting joints have also attracted lots of attention from all over the world in the past decades. This review paper introduces the research progress of superconducting joint technology. The first part briefly introduces the development of NMR superconducting magnet and superconducting joint. The second part summarizes the research progresses of superconducting joint between low temperature superconductor materials. The joint between high temperature superconductor materials is demonstrated in the third part. In the fourth part, the measurement technology regarding the resistance of superconducting joints is discussed. Finally, an outlook on superconducting joint research is presented for further discussion in the community.
