On June 27, China's key national science and technology infrastructure, the "Comprehensive Research Facility for the Key Systems of the Fusion Reactor Main Unit," marked a significant milestone. Its largest superconducting component, the Toroidal Field (TF) Magnet, concluded its final manufacturing phase and successfully passed expert acceptance. Additionally, the High-Temperature Superconducting (HTS) Central Solenoid Coil Magnet underwent full-parameter testing under operational conditions, demonstrating core performance that leads the world.

The TF Magnet, currently the largest superconducting magnet for fusion reactors globally, boasts impressive dimensions: 21 meters in length, 12 meters in width, and 3.3 meters in height, with a total weight of 582 tons. As a pivotal component of the facility, it plays a crucial role in constructing the toroidal magnetic field, which is essential for confining plasma and mitigating the impact and energy loss of high-energy particles on the vacuum vessel walls.

Notably, all key links in the entire magnet production chain have achieved domestic autonomy and controllability, with performance indicators that are at the forefront internationally. This achievement underscores China's growing prowess in the field of nuclear fusion technology and its commitment to advancing clean energy solutions.
