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

February 2, 2023 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.

U.S. Researchers Simulate Compact Fusion Power Plant Concept

The Compact Advanced Tokamak (CAT) concept uses physics models to show that by carefully shaping the plasma and the distribution of current in the plasma, fusion plant operators can suppress turbulent eddies in the plasma. This would reduce heat loss and allow more efficient reactor operation. This advance could help achieve self-sustaining plasma and smaller, less expensive power plants.
