Field-Reversed Configuration (FRC)
A high-beta compact toroid magnetic confinement concept where a closed-poloidal-field plasma torus is sustained inside a simple linear solenoid magnet.
Governing formula
Average Beta ⟨β⟩ ≈ 1 (High-Beta Compact Toroid)
SI unit
Dimensionless High Beta ⟨β⟩ ~ 0.9
In depth
Features high average plasma beta (⟨β⟩ ≈ 1) without central structural coils penetrating the torus hole, offering compact reactor geometry and potential for advanced Aneutronic (p-B11) fusion fuel cycles.
Examples in the real world
Commercial fusion research devices (TAE Technologies) pursuing compact FRC pulse reactors.
