Chinese researchers have achieved a major milestone in fusion energy research with the successful development of a high-performance linear plasma generator. The device, named the Superconducting Plasma Wall Interaction Linear Device (SWORD), has met its design specifications, positioning China as the second country in the world, after the Netherlands, to create such an advanced high-flux plasma generator. The announcement was made by the Hefei Institutes of Physical Science under the Chinese Academy of Sciences.
SWORD is a critical tool for advancing research into the “artificial sun,” a fusion facility designed to replicate the sun’s nuclear fusion process. By harnessing energy from abundant seawater resources, fusion technology promises a clean and virtually limitless energy source.
The device, inspired by the legendary Chinese sword Chixiao, measures 15.5 meters in length and weighs approximately 22.5 tonnes. It is capable of generating an impressive flux of 10²⁴ particles per square meter per second and can operate continuously for more than 24 hours. These capabilities make it an essential platform for testing plasma-facing materials, which are crucial for the development of fusion reactors.
An expert panel led by Ye Minyou, a professor at the University of Science and Technology of China, evaluated SWORD’s performance and confirmed that it has met all design specifications. This achievement marks a significant step forward in China’s quest to develop sustainable energy solutions through nuclear fusion.
Fusion energy, often referred to as the “holy grail” of clean energy, has the potential to revolutionize global energy systems by providing a safe, efficient, and environmentally friendly alternative to fossil fuels. With the successful development of SWORD, Chinese scientists are now better equipped to tackle the challenges of making fusion energy a reality.
