Tokamak Plasma Stable at Ten Times Old Theoretical Limit

Ohysicists at the University of Wisconsin-Madison produced a tokamak plasma that is stable at 10 times the [old] Greenwald limit. The findings may have implications for tokamak fusion reactors, though the researchers caution that their plasma is not directly comparable to that in a fusion reactor. Nearly 40 years ago, Martin Greenwald identified a density ...
