The research team of the Institute of Electrical Engineering of the Chinese Academy of Sciences Wang Qiuliang’s research group adopted a self-developed high-temperature interpolating magnet technology to increase the central magnetic field of YBCO interpolated magnets under the 15T superconducting back field to 24 @ 4.2K, making China a successor to the United States, Japan, and South Korea. After the realization of 24T full superconducting magnet countries. Compared with Bi2223 intercalated superconducting magnets, YBCO superconducting magnets have higher upper critical magnetic fields and critical currents, higher operating stability and easier access to extremely high magnetic fields. At present, only the National High Field Laboratory in the United States, the Tohoku University High Field Laboratory in Japan, and South Korea's SuNAM Superconducting Company can realize a full superconducting magnet of 24T or more. Wang Qiuliang’s research team used YBCO strips to develop high-field interpolated magnets under the auspices of the National Natural Science Foundation. The researchers adopted a hierarchical design to improve the safety margin of the entire coil. A specially designed welding device was used to make a magnet joint with excellent performance. The resulting interpolated magnets were tested under liquid nitrogen conditions when the operating current was 32 A. The magnet reached 1.62T@77K. Under the liquid helium test condition, the interpolating magnet generates a 9T center magnetic field in the superconducting back field of 15T when the operating current is 167A, thus realizing a 24T full superconducting magnet in the center field, and the highest field is 24.3T. The realization of the 24T extremely high-field superconducting magnetic field signifies that China has been at the forefront in the development of high-field interpolated magnets, and it also indicates that China has gradually absorbed and mastered the production technology of extremely high-field magnets and accumulated rich experience. It lays the foundation for the realization of GHz class spectrometer magnets and extremely high field and large scientific devices.
