PC Revue | Fusion Energy: China's "Artificial Sun" reached a temperature of 100 million degrees Celsius

Again, we are one step closer to the source of unlimited net energy from nuclear fusion. During a four-month experiment on the advanced Tokamak Superconductor (EAST), Artificial Sun managed to achieve a plasma temperature of more than 100 million degrees Celsius six times the temperature inside the Sun and keep it for about 10 seconds.

EAST is a tokamak reactor consisting of a metal ring and a vacuum "cone" into which the hydrogen atoms are introduced. These are then heated in various ways to create plasma which is then compressed using a group of powerful superconducting magnets.

Finally, the plasma becomes so hot and so compressed that the conditions in the reactor resemble those in the Sun. This forces the atoms of hydrogen to bind and release an enormous amount of energy. If a reactor could be built in which the fusion reaction would be maintained by itself, it could produce more energy than it consumes.

EAST scientists have used a combination of four different heating methods to create creature and start a fusion process. Their goal, however, was not to reach a record but to explore how the creature can maintain stability and balance, how it can be "trapped" and transferred, and how plasma walls interact with energy particles.

EAST Tokamak is used to investigate methods to keep plasma electron temperatures above 100 million ° C for a longer period of time. Such research could help in the development of advanced reactors such as the International ITER Thermonuclear Experimental Reactor in France, the Chinese Technical Fusion Test Reactor or the planned DEMO Power Station.

Achieving temperatures above 100 million degrees Celsius, although only for 10 seconds, proves that it can be done at the temperatures required for nuclear fusion.
