"Chinese artificial sun" sets new world record (2)

Staff members perform an upgrade to the experimental advanced superconducting tokamak (EAST) at the Hefei Institutes of Physical Science under the Chinese Academy of Sciences (CAS) on April 13, 2021. Chinese scientists have set a new world record of achieving a plasma temperature of 120 million degrees Celsius for a period of 101 seconds in the latest experiment on Friday, a key step toward the test running of a fusion reactor. 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.
