- Chinese scientists set a new world record by generating a steady magnetic field of 351,000 gauss using a fully superconducting magnet.
- The breakthrough will advance the commercialization of superconducting scientific instruments like nuclear magnetic resonance spectrometers.
- The magnet provides technical support for fusion magnet systems, space electromagnetic propulsion, and other cutting-edge fields.
- Developed by ASIPP in collaboration with several institutions, the magnet uses high-temperature superconducting insert-coil technology.
- The team overcame challenges like stress concentration and shielding current effects, improving stability and performance.
- The magnet was energized to 35.1 tesla, operated stably for 30 minutes, and safely demagnetized, verifying reliability.
- The achieved magnetic field strength is over 700,000 times Earth's geomagnetic field, surpassing the previous record of 323,500 gauss.
- Such magnets are key for magnetic confinement fusion devices, forming a 'magnetic cage' for high-temperature plasma.
- ASIPP has achieved complete localization of superconducting materials, devices, and systems, contributing to ITER projects.
