China's Artificial Sun Reaches 100,000,000° CS. Himmelstein | November 19, 2018
China’s Experimental Advanced Superconducting Tokamak (EAST) reactor has exceeded 100,000,000° C, setting a new record in fusion technology. The temperature, attained during the four-month test conducted at Hefei Institutes of Physical Science of the Chinese Academy of Sciences (CASHIPS), is about seven times hotter than the interior of the Sun.
Researchers applied advanced plasma control and theory and simulation prediction, as well as lower hybrid wave, electron cyclotron wave, ion cyclotron resonance and neutral beam ion heating techniques, to optimize the plasma current density profile in EAST. This resulted in power injection greater than 10 MW and an increase in plasma stored energy to 300 kJ.
The superconducting tokamak achieved a fully non-inductive, steady-state scenario with extension of fusion performance at high density, high temperature and high confinement. Data documented during experiments with China’s "artificial sun" validate heat exhaust, transport and current drive models, and fine-tune fusion performance predictions for the Chinese Fusion Engineering Test Reactor. This third-evolution machine is being designed with a toroidal magnet field of 6.5 to 7 Tesla and a plasma current of 13 MA.
