Princeton put AI in charge of a fusion-plasma control loop running every 20 milliseconds; in one test it predicted a damaging instability 200 ms early and stopped it before it began - The Times of Ind...
Inside a steel vault at the Princeton Plasma Physics Laboratory, a superheated whirl of charged particles spins in near vacuum, held in place by invisible magnetic fields. This is a fusion plasma, the same kind of matter that powers the Sun, and it is notoriously difficult to control.
