HL-2M Tokamak, the new generation of China's "artificial sun," has been successfully installed and finished its first discharge in Chengdu, southwest China's Sichuan Province, marking a major breakthrough in the country's nuclear fusion, December 4, 2020. / CFP

The "artificial sun", able to generate ultra-high temperature 10 times as hot as the sun, aims to produce clean energy through controlled nuclear fusion that replicates natural reactions that occur in the sun. / CFP

The successful installation and discharge of HL-2M indicates China has acquired the ability to independently design, construct and operate technologies of a large-scale advanced tokamak device, thus laying a solid technical foundation for the country to achieve high-quality development in nuclear fusion. / CFP

HL-2M is the largest advanced tokamak device with the highest parameters in China, expected to serve as a platform for the country to achieve international cooperation in nuclear fusion energy. / CFP
