How Tokamak Fusion Reactors Actually Work (2026)
How tokamak fusion reactors actually work, explained from first principles: plasma confinement, magnetic fields, the triple product, and why net energy is so hard.
How Tokamak Fusion Reactors Actually Work: The Physics of Confining a 150-Million-Degree Plasma
The complete physics of tokamak fusion — magnetic confinement, plasma heating, the Lawson criterion, instabilities, and why it's so hard to sustain fusion. From first principles to ITER and beyond.
