Researchers working on China’s ‘artificial sun’ have reported breaking a long-accepted threshold that has limited the operation of nuclear-fusion reactors for decades. China’s Experimental Advanced Superconducting Tokamak (EAST) is a nuclear-fusion research reactor in Hefei. Researchers hope that it will one day produce clean, nearly limitless energy by replicating the fusion processes that power the Sun.One of the most promising reactor designs, the tokamak, confines plasma inside a doughnut-shaped chamber using magnetic fields. The plasma is then heated. To sustain fusion reactions, the plasma must reach an extremely high density meaning many particles must be packed into a small volume. Do you think that plasm is likely to be unstable ?
