Controlling a Plasma Hotter Than the Sun's Core

From the NovaLogic Blog · Fusion Energy, Engineered

A fusion plasma sits at a hundred million degrees, far hotter than the core of the Sun, and it does not want to stay put. Left alone, it wriggles, drifts, and finds instabilities that dump its energy into the wall.

Confinement is therefore not a static condition you set up once. It is a control problem. Magnetic fields have to be adjusted continuously, on millisecond timescales, in response to how the plasma is actually behaving moment to moment.

This makes plasma physics inseparable from real-time control engineering. The reactor needs sensors that see the plasma state, models that predict where it is heading, and actuators fast enough to correct it before an instability grows.

NovaLogic treats plasma control as a first-class system, drawing on the same kind of feedback and estimation techniques that stabilize aircraft and rockets, applied to the hardest fluid humanity has tried to tame.
