Heating by cooling

The field of magnetic fusion research has mysteries to spare. How to confine turbulent plasma fuel in a donut-shaped vacuum chamber, making it hot and dense enough for fusion to take place, has generated questions—and answers—for ...

China's quest for clean, limitless energy heats up

A ground-breaking fusion reactor built by Chinese scientists is underscoring Beijing's determination to be at the core of clean energy technology, as it eyes a fully-functioning plant by 2050.

Not all ions in tokamaks go with the flow

For the first time, scientists are measuring the rotation of the main (deuterium) plasma in the edge region of a fusion device. New spectroscopic measurements combined with state-of-the-art spectroscopic simulation made this ...
