AI can now control fusion plasma faster than humans can react
Princeton researchers have tested an AI system that can monitor and control fusion plasma in milliseconds, reacting far faster than a human operator.
Princeton researchers have tested an AI system that can monitor and control fusion plasma in milliseconds, reacting far faster than a human operator.
The short version
- In one experiment, it predicted a damaging instability about 200 milliseconds before it appeared and adjusted the plasma to stop it from forming.
- The framework is called PACMAN (a novel abbreviation for Prediction And Control using MAchiNe learning).
- Researchers successfully tested it on a real fusion system in five separate experiments.
What happened
Its design and initial results are described in a new paper published in the journal Nuclear Fusion . Fusion has the potential to provide a virtually unlimited supply of electricity.
Why it matters
Researchers are exploring several approaches to making fusion practical on Earth, including machines known as tokamaks.
