UrduEdge localized modes (ELMs) associated with plasma instabilities in tokamak fusion reactors can damage reactor walls, a challenge in the design of future fusion power plants. Scientists have now discovered that internal resistance of the plasma can cause additional instabilities that drive ELMs in the National Spherical Torus Experiment. This will help researchers mitigate and control ELMs in spherical tokamaks.

Flipping the Script with Reverse D-Shaped Plasmas
Mirrored D shape demonstrates surprisingly high pressures in a tokamak, indicating a shape change may be in order for next-generation fusion reactors. The Science To harness the reaction at the heart of our sun, fusion reactors must hold a large…
