Which country is experimenting with an “artificial sun,” dubbed Experiential Advanced Superconducting Tokamak (EAST)?
Russia
Norway
China
Argentina
Answer: China
China’s ‘artificial sun’ broke a new record by operating at 70 million degrees Celsius for 1,056 seconds, or more than 17 minutes. The record was set on December 30th.
According to media sources, the temperature reached is nearly five times that of the sun.
According to the Chinese Academy of Sciences, the continuous high-temperature plasma operation is the world’s longest of its kind.
The previous record was established in May by the Experimental Advanced Superconducting Tokamak (EAST), which ran for 101 seconds at a temperature of 20 million degrees Celsius. The goal of EAST is to develop nuclear fusion similar to that found in the sun in order to provide clean energy.
Xianzu, a researcher at the Chinese Academy of Sciences’ Institute of Plasma Physics, was in charge of this experiment, and he was the one who announced it.
“We achieved a plasma temperature of 120 million degrees Celsius for 101 seconds in an experiment in the first half of 2021,” said Xianzu. “This time, steady-state plasma operation was sustained for 1,056 seconds at a temperature close to 70 million degrees Celsius, laying a solid scientific and experimental foundation toward the running of a fusion reactor,” he added.
Nuclear fusion power works by smashing heavy hydrogen atoms to produce helium, releasing a large amount of energy in the process.
