Field-Reversed Configuration (FRC) Physics
Offers the highest plasma beta of magnetic confinement concepts, minimizing reactor size and mass.
01 Definition
The physics of closed-field, high-beta compact toroids containing primarily poloidal magnetic fields with negligible internal toroidal field.
02 Detailed_Analysis
Field-Reversed Configuration (FRC) Physics governs a class of compact toroid plasmas characterized by closed field lines produced entirely by internal diamagnetic eddy currents, with little to no toroidal field component. FRCs exhibit high plasma beta (volume-averaged beta near unity), a linear cylindrical geometry that facilitates translation and compression, natural divertor topology, and compatibility with direct energy conversion and inductive pulsed propulsion architectures.
03 Key_Facts
- ▸ Exhibits volume-averaged beta (β) values approaching unity (β ≈ 0.8–1.0)
- ▸ Possesses purely poloidal closed magnetic topology with open exhaust sheath
- ▸ Allows axial translation, merging, and high-ratio magnetic compression
- ▸ Researched heavily in experiments like FRX, FRCHX, IPA, and C-2U
