Faster fusion with AI?

An artist’s interpretation of the inside of a fusion vessel, where some of the inner surfaces are directly exposed to the plasma. Some regions lie in the “magnetic shadow” of other components and are therefore magnetically shielded from the intense heat of the plasma. (Image: Kyle Palmer/PPPL Communications Department)
The article “Finding the shadows in a fusion system faster with AI,” published by the Department of Energy’s Princeton Plasma Physics Laboratory, details the public-private partnership among PPPL, Commonwealth Fusion Systems, and Oak Ridge National Laboratory. The partnership has led to a new artificial intelligence approach that is faster at finding what’s known as “magnetic shadows” in a fusion vessel: “safe havens protected from the intense heat of the plasma.”
