Construction and Working Principle of Tokamaks
The tokamak uses a toroidal magnetic cage to isolate hot plasma from vessel walls. Thermonuclear fusion can be ignited inside after reaching suitable conditions. More than 50 tokamaks are involved in fusion research today.

Tokamaks
The word "tokamak" is of Russian origin and means "toroidal chamber and magnetic coils." This magnetic confinement system holds plasma in magnetic fields of toroidal shape. The first tokamak, the T-1, started operation in 1958 in Russia, and since then the greatest advances in th

Magnetic Confinement
Charged particles follow magnetic field lines. Tokamaks and stellarators twist those lines into a torus so plasma cannot leak out too quickly.
