Scientists produce tokamak plasma that's stable at 10x Greenwald limit
Physicists at the University of Wisconsin–Madison produced a tokamak plasma that is stable at 10 times the Greenwald limit.
The new study published in is part of tokamak experiments in the Madison Symmetric Torus with a density up to an unprecedented level of about ten times this limit. Unlike other tokamaks, the metal donut that houses the MST plasmas is thick and highly conducting, allowing for more stable operation, according to University of Wisconsin. The researcher also underlined that these results are unlikely to be directly applicable to fusion reactors, such as ITER and others that are being built in the hopes of being the first net-positive energy production tokamaks.
