UrduThe plasma in a fusion device can erode device walls, releasing particles in a process called sputtering. These particles can reduce a device’s performance and lifespan. In this study, researchers examined how the smoothness of device surfaces changes at small scales over time and how this affects erosion. This research will aid in the future design and operation of fusion power plants.

Predicting Explosive Energy Bursts in Compact Fusion Power Plants
Edge 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…
