Chinese language combine software pushes 100 million previous levels [Report]



Tokamak Superconducting Advanced Experimental (EAST), named "artificial Chinese sun", achieved an electron temperature of over 100 million degrees in its core plasma during the four-month trial this year. This is about seven times more than in the sun, which is about 15 million degrees C.


The experiment shows that China is making significant progress towards tokamak-based combustion-based energy generation.

The experiment was carried out by the Eastern team in Hefei, the Chinese Science Academy Physical Sciences Institutions (CASHIPS) in association with domestic and international colleagues.

The current plasma density profile was optimized through the integration and effective synergy of four types of heating power: lower hybrid wave heating, electronic cyclotron wave heating, ion cyclotron heating and neutral beam hood heating.

The power injection was more than 10 MW, and a plasma-powered energy was given to 300 kJ after scientists made the best of combining different heating techniques. The experiment used advanced plasma control and theory / simulation predictions.

The scientists conducted experiments on plasma balance and instability, restrictions and transportation, plasma interaction and active particle physics to show a long-standing, stable stable H-mode mode operation with good control of independence, core / edge MHD stability, and heat heating using tungsten diversion similar to ITER.

With similar ITER operating conditions such as radiofrequency waves, lower torque, and water-resistant tungsten diversion, the East has a steady, non-intuitive single position with an extension of high density, high temperature and high density integration performance .

Meanwhile, to solve the particles and power, which are essential for high performance stable operations, the East East team employed many techniques to manage the methods that have been located on tungsten edges and disorders with metal walls, as well as managing active feedback to the heat load diversion.

Action scenarios, including the temperature of constant H-mode and electronic performance models over 100 million degrees in the East, have made unique contributions to ITER, Chinese Fusion Engineering (CFETR) and DEMO Test Reactor.

These results provide key data for validating current heating, transport and driving models. They also increase confidence in the forecast performance predictions for CFETR.

At present, the design of the CFETR physics focuses on the optimization of a third evolution machine with a large radium of 7 m, a 2 m small radium, an existing 6.5-7 Tesla and plasma 6.5-7 magnetic field of 13 MA.

In support of the future development of CFETR and DEMO engineering, the National National Mega Science Project – the Comprehensive Research Facility – will be launched at the end of this year.

This new project will develop the development of tritium blanket test modules, superconducting technology, relevant reactor heating and current actuators and driving sources, and referral materials.

EAST is the first poisonous tokamak with a transcript that is not a newsletter in the world. It was designed and built by China focusing on key science issues that apply to joining power. Since its inception in 2006, East has become an open-ended probation facility where a world-wide community can carry out constant state-of-the-art operations and physiological research related to ITER.
