China's 'artificial sun' sustains plasma for record 100 secs
China's nuclear fusion reactor, Experimental Advanced Superconducting Tokamak (EAST), sustained plasma in a steady state high confinement mode for 101.2 seconds, the longest ever recorded time for such type of reaction. Tokamaks are dubbed as "artificial sun" as temperatures in the reactors can reach up to 300 million Â°C, nearly 20 times that in the Sun's core.
