The HL-2M Tokamak, China’s next-generation “artificial sun,” is expected to be operational in 2020 as installation work has gone smoothly since the delivery of the coil system in June.
Chinese scientists are close to deployment “artificial sun” in 2020, state media reported, adding that the device will be able to provide clean energy through controlled nuclear fusion.
“The HL-2M tokamak, China generasi’matahari artificial, ‘is expected to be operational in 2020 as the installation work has gone smoothly since the delivery of the coil system in June,” the official news agency, Xinhua reported this week.
The device works by replicating the natural reaction that occurs in the sun by using hydrogen and deuterium gas as a fuel.

“New Officers, with more advanced structure and mode of control, is expected to generate plasma hotter than 200 million degrees Celsius,” said Duan Xuru, head of the Western Institute of Physics under the China National Nuclear Corporation was quoted by Xinhua as saying.
The report added that the artificial sun will provide key technical support for China’s participation in the project International Thermonuclear Experimental Reactor (ITER), as well as self-design and build a fusion reactor.
“China is among the seven members of the funding of ITER, nuclear fusion research and engineering project to build an international tokamak nuclear fusion reactor in France, considered the largest magnetic confinement physics experiments in the world,” reports the news site Caixin.
In 2018, the experimental advanced superconducting Tokamak (EAST), or the country’s first “artificial sun China” reached the electron temperature of more than 100 million degrees in the plasma core, a key step toward running test fusion reactor, a laboratory in eastern China’s Anhui province said.
“The main purpose of EAST is to create nuclear fusion like the Sun using deuterium is abundant in the sea to provide a stream of clean energy,” Xianzu Gong, director of the trial, had then said.
The temperature reached at the EAST trial about seven times more than the interior of the Sun, which is around 15 million degrees Celsius.
Gong said the experimental temperature is around 50 million degrees Celsius in 2017.
