Controller with Integrated Machine Learning Tweaks Fusion Plasmas in Real Time

sarah JonasResearch Results

The conditions for high fusion performance in fusion devices can result in damaging energy bursts called edge-localized modes (ELMs). ELMs can be stabilized through small adjustments to the magnetic confinement field, but this approach is usually limited to manual, preprogrammed responses. In this research, scientists integrated machine learning with adaptive control to achieve real-time adjustment capable of responding to the dynamic conditions of a fusion plasma in the DIII-D National Fusion Facility and Korea Institute of Fusion Energy KSTAR tokamaks.

Stuck in the Rough: How Aging Reactor Walls May Exhibit Lower Erosion

sarah JonasResearch Results

The 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

sarah JonasResearch Results

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.
