China Develops Advanced Plasma Generator, Taking Second Place Globally
HEFEI, Jan 15 (Xinhua) -- The Hefei Institutes of Physical Science under the Chinese Academy of Sciences announced on Tuesday that it has successfully developed a linear plasma generator known as the Superconducting Plasma Wall Interaction Linear Device (SWORD), marking China's breakthrough in high-flux plasma generator technology.
This cutting-edge device, measuring 15.5 meters long and weighing approximately 22.5 tonnes, has reached design specifications, placing China second globally only after the Netherlands in developing such advanced plasma generators. SWORD is a vital tool for developing key materials for the "artificial sun," a fusion facility designed to harness clean and sustainable energy.
Inspired by Chixiao, a legendary sword from ancient China, SWORD features a streamlined design while generating an extraordinary 10²⁴ particles per square meter per second and operating continuously for over 24 hours. An expert panel led by Ye Minyou, a professor at the University of Science and Technology of China, concluded that the device has met the design specifications.
This significant achievement enables rigorous testing of plasma-facing materials critical for fusion devices, which aim to replicate the sun's nuclear fusion process using abundant substances from seawater to generate clean energy. Researchers are optimistic about unlocking new possibilities in clean energy production with SWORD's successful development.
Zhou Haishan, a researcher at the Advanced Study Institute of Physics with Plasmas (ASIPP) under the Hefei Institutes of Physical Science, expressed relief and gratitude after overcoming significant technical challenges over five years to develop SWORD. He noted that this success supports research on China's next-generation experimental fusion reactors and will also be available for international collaboration.
The development of SWORD marks an important milestone in China's nuclear energy research, pushing the country closer to achieving its ambitious renewable energy goals while contributing positively to global clean energy initiatives.
