Nuclear magnetic resonance spectrometers, which play a crucial role in medical imaging and chemical analysis, stand to benefit greatly from this innovation.
Beyond these applications, the magnet’s capabilities extend to other cutting-edge technologies. It offers essential technical support for fusion magnet systems, space electromagnetic propulsion, and superconducting induction heating. These areas require exceptionally strong and stable magnetic fields to achieve optimal performance. According to Liu Fang, a researcher at the Institute of Plasma Physics of the Chinese Academy of Sciences (ASIPP), the magnet employs high-temperature superconducting insert-coil technology. This is combined with low-temperature superconducting magnets to maintain stability under extreme conditions.
Overcoming Technical Challenges
Developing a magnet of this capability was not without its hurdles. The engineering team faced several significant challenges in achieving the record-breaking performance. Issues such as stress concentration, shielding current effects, and multi-field coupling effects posed obstacles in the low-temperature and high-field environments necessary for the magnet’s operation.
By addressing these technical challenges, the researchers were able to enhance both the mechanical stability and electromagnetic performance of the magnet. The new design ensures that the system can remain stable during prolonged operations without performance degradation. During testing, the magnet was energized to 35.1 tesla and maintained steady operation for 30 minutes, after which it was safely demagnetized. This successful trial confirmed the reliability of the new approach, indicating that the technology can endure extended use under demanding conditions.
Applications in Fusion and Beyond
Superconducting magnets are integral to the development of magnetic confinement fusion devices, which rely on powerful magnetic fields to contain plasma at extremely high temperatures. This containment is essential for sustaining nuclear fusion reactions, a potential source of virtually limitless clean energy. ASIPP has been a leader in fusion research, achieving complete localization of superconducting materials and systems in China, thereby reducing the need for imports.
As a primary Chinese participant in the International Thermonuclear Experimental Reactor (ITER) project, ASIPP is responsible for several critical components, including superconductors, correction coils, and magnet feeders. These components are crucial for supporting the world’s largest fusion experiment, highlighting China’s significant contribution to global fusion research efforts. The new record in superconducting magnet performance not only enhances China’s role in this international endeavor but also sets the stage for a new generation of technological advancements.
The Global Impact of China’s Achievement
China’s latest milestone in superconducting technology has implications that extend far beyond its borders. The magnetic field strength achieved is over 700,000 times that of Earth’s natural magnetic field, emphasizing the magnitude of this breakthrough.
