Chinese Team Develops Innovative Plasma Device to Advance 'Artificial Sun' Research

A research group from the Hefei Institutes of Physical Sciences, part of the Chinese Academy of Sciences, has successfully engineered a robust linear plasma device known as "Chixiao." This innovative device is intended to support the ongoing research aimed at developing core materials necessary for the "artificial sun," which is associated with controlled nuclear fusion experiments. As reported by Xinhua News Agency, it was confirmed on Tuesday that the Chixiao device fulfills its design specifications after being evaluated by experts, positioning China as only the second country in the world to have such technology after the Netherlands.

The endeavor to create an "artificial sun" is overshadowed by numerous challenges, particularly in creating super materials that can withstand the intense forces of plasma particle flows that construct the “wall” of this fusion reactor. Zhou Haishan, a key researcher at the Institute of Plasma Physics, explained that future advancements in creating a functional "artificial sun," which aims to produce sustainable electricity over extended durations, necessitate advanced simulation environments. These environments are crucial to testing whether the newly designed materials can endure the rigorous conditions expected in a nuclear fusion reactor.

Zhou and his team have invested over five years into the Chixiao project, resulting in a device that can emit an astonishing number of particles at a rapid rate while maintaining continuous operation for substantial periods. The Chixiao device, measuring 15.5 meters in length and weighing 22.5 tons, has been aptly named after Chixiao, one of ancient China’s legendary swords, owing to its elegant and aerodynamic design. The successful review and validation of Chixiao's parameters mark a significant milestone, reinforcing China's position as a leader in nuclear fusion research while also laying the groundwork for future collaborative efforts across the globe.
