Princeton's PACMAN AI Controls Fusion Plasma in 20 Milliseconds, Achieving 94% Disruption Detection Rate
Researchers at Princeton Plasma Physics Laboratory have developed PACMAN, an AI framework that monitors and controls fusion plasma 50 times per second — far faster than any human operator can respond. The system predicted damaging plasma instabilities up to 200 milliseconds in advance and achieved a 94% early disruption detection rate, providing critical warning windows. The framework keeps humans in charge of high-level goals while delegating millisecond-to-millisecond control decisions to AI.
