Nicknamed Chinese artificial sun, the Experimental Advanced Superconducting Tokamak (EAST), has achieved over 100 million degrees electron temperature in the core plasma in its four-month-long experiment campaign.
EAST team in Hefei Institutes of Physical Science, Chinese Academy of Sciences, in colaboration with domestic and international colleagues, made significant progress along the China’s roadmap towards tokamak based fusion energy production.
By effectively integration and synergy of four kinds of heating power, namely, lower hybrid wave heating, electron cyclotron wave heating, ion cyclotron resonance heating and neutral beam ion heating, the plasma current density profile was optimized.
The power injection exceeded 10MW, and plasma stored energy boosted to 300 kJ after scientists optimized the coupling of different heating techniques, and utilized advanced plasma control, theory/simulation prediction. The electron temperature of the core plasma increased beyond 100 million degrees.
