New light shed on pesky “snakes” that cool fusion reactions (Physical Review Letters)

By John Greenwald, Princeton Plasma Physics Laboratory Corkscrew-shaped instabilities called “snakes” have long been a common feature of the hot, electrically charged plasma gas that fuels fusion reactions, which could provide a future source of clean and abundant energy for generating electricity. Such snakes trap impurities released from the plasma-facing walls of experimental fusion vessels … Continue reading New light shed on pesky “snakes” that cool fusion reactions (Physical Review Letters)
