Congratulations to the Institute of Plasma Physics for the development of a fully REBCO high-temperature superconducting magnet capable of generating a magnetic field of 26.8T, with Shanghai Superconductor supplying high-performance HTS tapes.

2024-02-04

On January 30, 2024, the Institute of Plasma Physics and its collaborative research team achieved a significant breakthrough in high-temperature superconducting magnet technology. The project was led by the Institute of Plasma Physics and jointly developed by Hefei International Applied Superconductivity Center, Institute of Energy of Hefei Comprehensive National Science Center, Hefei Nuclear Fusion Magnet Technology Co., Ltd., Tsinghua University, and Hefei Xihe Superconductivity Technology Co., Ltd. The all REBCO high-temperature superconducting magnet generates a central magnetic field of 26.8T under liquid helium, breaking the previous record of 26.4T. This achievement signifies that China's technology and material performance in high-temperature superconducting magnets have reached an internationally leading level.

Shanghai Superconductor provided a variety of high-performance high-temperature superconducting tapes for the magnet’s winding, offering key material support for the successful development of the magnet.

Shanghai Superconductor has maintained a close cooperative relationship with the Institute of Plasma Physics for a long time. It has previously supplied high-performance high-temperature superconducting tapes for various magnets, including the 19.4T CICC-like magnet, 19.8T and 24T all superconducting hybrid magnets, and the 24.1T full REBCO magnet, all of which successfully met the design specifications. In the future, SST will continue to deepen its cooperation with the Institute of Plasma Physics to make greater contributions to the development and innovation of high-temperature superconducting magnet technology.
