Stuck in the Rough: How Aging Reactor Walls May Exhibit Lower Erosion
Department of Energy, Office of Science

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.

Electric space propulsion systems use energized atoms to generate thrust. The high-speed beams of ions bump against the graphite surfaces of the thruster, eroding them a little more with each hit, and are the systems' primary lifetime-limiting factor.

Theorists Propose a Novel Way to Measure Gluons’ Orbital Motion
Department of Energy, Office of Science

Subatomic particles’ spin dictates how they propagate, interact, and form bound states. But how proton spin arises from quarks and gluons is a mystery, and experimental measurements of the individual contributions of quark and gluon spin don’t add up to the proton’s total spin. The orbital motion of quarks and gluons in the proton may account for the rest. Theorists have now proposed a way to measure this property using the future Electron-Ion Collider.
