Major breakthroughs in China's science and technology in 2021

11. 'Chinese artificial sun' sets new world record

In an experiment on May 28, Chinese scientists set a new world record of achieving a plasma temperature of 120 million degrees Celsius for 101 seconds, a key step toward the test running of a fusion reactor.

The breakthrough was announced by Gong Xianzu, a researcher at the Institute of Plasma Physics of the Chinese Academy of Sciences, and in charge of the experiment conducted in Hefei, capital of East China's Anhui province.

The experiment at the experimental advanced superconducting tokamak (EAST), or the "Chinese artificial sun," also realized a plasma temperature of 160 million degrees Celsius, lasting for 20 seconds.
