A new breakthrough has been achieved in the superconducting magnets used in our country's two nuclear fusion reactors.

Today, the Institute of Plasma Physics of the Hefei Institutes of Physical Science, Chinese Academy of Sciences made new progress in the "Artificial Sun" project. Two independently developed nuclear fusion reactors using superconducting magnets have completed technical acceptance and full-operational parameter testing. Among them, the largest superconducting component of the national major scientific facility "Integrated Research Facility for Fusion Reactor Key Systems" - the toroidal field magnet, has completed its final preparation process and passed expert technical acceptance. In the future Science City of Hefei, adjacent to the Integrated Research Facility for Fusion Reactor Key Systems, another key component of a nuclear fusion large scientific device - the high-temperature superconducting central solenoid coil magnet of the compact fusion energy experiment facility, has also made significant progress. Today, the magnet completed full-operational parameter testing, with its core performance reaching an international leading level.
