Chinese Academy of Sciences "Artificial Sun" Experimental Device Obtains Major Achievements Reporter learned from the Hefei Institute of Materials Research, Chinese Academy of Sciences on the 5th that the large-scale scientific project "Artificial Sun" Experimental Device (EAST) undertaken by the Institute's plasma has obtained major experimental results and its auxiliary heating project The neutral beam injection system (NBI) successfully achieved the 100-second long-pulse hydrogen neutral beam extraction on the integrated test platform, and initially verified the long-pulse operation capability of the system. Scientists said that the long pulse neutral beam extraction obtained in this round of experiments is the first in China, marking another solid step in the field of neutral beam injection heating research in China. The EAST neutral beam injection system is completely developed by China itself, covering many scientific and technical fields such as precision high-current ion source, high vacuum, and low temperature refrigeration.
