Stellarator

Fusion

Magnetic fusion device with 3D external coils.

A stellarator creates a confining helical magnetic field using shaped external coils rather than a large plasma current.

Stellarators

Stellarators are "generators of stellar energy", and their principle was discovered before tokamaks. A helical-twisted magnetic field, necessary for successful plasma confinement, is generated only by magnetic coils of various shapes. The stellarator is a device capable of contin
