Previously, researchers led by Kolemen successfully deployed a separate AI controller to predict and avoid another type of plasma instability in real time at the DIII-D tokamak.

"The model refines the thinking on stabilizing the edge of the plasma for different tokamak shapes," said Jason Parisi, a staff research physicist at PPPL.

Light can also help heat the plasma within ring-shaped devices known as tokamaks as scientists worldwide strive to harness the fusion process to generate green electricity.

A tokamak is a donut-shaped device that uses magnetic fields to hold a plasma.

DIII-D is a tokamak, a device that uses magnetic fields to confine a fusion plasma in a donut shape.
