Spherical Tokamaks: Compact Fusion Innovation

A spherical tokamak is a smaller, rounder version of a normal tokamak — still a fusion

machine, but shaped more like a squished donut or a cored apple.

🌍 Simple definition A spherical tokamak (ST) is a fusion device that uses magnetic fields

to trap super-hot plasma, just like a regular tokamak, but with a much

smaller hole in the middle. This makes it more compact, cheaper,

and able to reach high pressures. 🧲 How it differs from a regular tokamak: Regular Tokamak

Spherical Tokamak Big donut shape Very round, tight donut Large hole in center

Tiny hole in center Larger, heavier magnets Smaller, simpler magnets
