Alcator C-Mod

A compact, high-field tokamak that showed the payoff of strong magnetic fields.

Type

High-field tokamak

Lesson

High field, compact

Alcator C-Mod was a compact, high-field copper-magnet tokamak that demonstrated the performance benefits of strong fields in a small machine — the very principle high-temperature superconductors now let Kronos pursue continuously at 16.84 T.

It is intellectual heritage for the compact, high-field approach.
