China Develops Artificial Sun That Can Reach 100million Degree Celsius

While some countries are still battling with infrastructures, potholes, electricity among others, China is thinking of having its own Sun to power the earth.

Scientists at the Hefei institutes of physical science, part of the Chinese Academy of Sciences (CASHIPS), have developed a nuclear fusion reactor that achieved 100 million degrees Celsius in its core plasma during a four-month experiment this year. Nicknamed the ‘Chinese Artificial Sun’, the Experimental Advanced Superconducting Tokamak (EAST) can reach temperatures seven times hotter than the core of the real sun, which is about 15 million degrees Celsius.

EAST is the first fully superconducting Tokamak with a non-circular cross-section in the world, designed and constructed by China with a focus on key science issues related to the application of fusion power. The Chinese scientists, in collaboration with domestic and international colleagues, carried out experiments on plasma equilibrium and instability, confinement and transport, plasma-wall interaction and energetic particle physics to demonstrate long-time scale, steady-state H-mode operation with good control of impurity, core/edge MHD stability, and heat exhaust using an ITER-like (international thermonuclear experimental reactor) tungsten divertor.

The experiment shows China is making significant progress towards Tokamak-based fusion energy production, which could provide the basis for a limitless source of clean energy.
