Scientists from the Chinese Academy of Sciences (CAS) have reported a major advance in nuclear fusion research, after their experimental reactor achieved plasma density levels once thought impossible.
The breakthrough was made on CAS’s so-called «artificial Sun», the Experimental Advanced Superconducting Tokamak (EAST), where researchers successfully stabilised ultra-dense plasma beyond the long-standing Greenwald Limit, a theoretical barrier that has constrained fusion performance for decades.
Using a new method known as plasma-wall self-organisation, the team was able to prevent the plasma from becoming unstable even at unprecedented density levels. According to the researchers, this opens the door to significantly...
