The reporter learned from the Chinese Academy of Sciences Hefei Institute of Materials Science on the 2nd that the EAST, an experimental device of the National Large Science and Engineering “Artificial Sun†undertaken by the Institute of Physics of the PLA, made a major breakthrough in the 11th round of physical experiments and achieved a steady state of more than 60 seconds. High confinement mode plasma discharge. EAST has thus become the first Tokamak nuclear fusion experiment device to achieve steady-state high-constrained mode operation lasting minutes.
According to senior experts in international magnetic confinement fusion and director of the advanced plasma physics department at the Japan Nuclear Fusion Institute, Kazuya Sada, he believes that it is of great significance to the future International Thermonuclear Experimental Reactor (ITER) program.
In the pure RF wave heating, tungsten divertor and other conditions, the realization of steady-state high confined mode plasma discharge is one of the basic operating modes of ITER.
The 2012 EAST physics experiment created a 32-second high binding mode world record. In recent years, EAST has successively completed upgrades of auxiliary heating, tungsten divertors, and plasma physics diagnostics systems, overcoming key technical challenges such as heating and current drive, distributed parameter measurement, and in-depth research and fundamental solutions to RF wave coupling and high resolution. A series of physical problems such as constrained plasma stability control, heating under low-momentum conditions, and current-driven transport have laid a solid foundation for the realization of long-pulsed high-constrained-mode plasmas.
The EAST team obtained steady-state high-constrained-mode plasma discharges for more than 60 seconds in this round of experiments, which not only fully and significantly exceeded the 2012 results in terms of plasma parameters, constrained performance, and duration of maintenance, but also achieved complete non-induction currents. Drive (ie, steady state).
It is understood that ITER will use the low-flux injection operation mode dominated by RF waves and the active water-cooled tungsten divertor structure. EAST is the only fully superconducting tokamak with the two major characteristics and long pulse capability in the world. Its steady-state operation mode will provide important reference for ITER and future nuclear fusion reactors. (Reporter Cai Min)
