By eliminating bulky formation systems, the design lowers cost and improves scalability. Its magnetically efficient, high–power-density FRC can theoretically produce up to 100 times more fusion power than a same-sized tokamak. The linear, modular structure is easier to build, maintain, and scale, helping overcome fusion’s historical economic barriers.
The system is optimized for hydrogen-boron (p-B11) fuel, an aneutronic reaction that produces virtually no high-energy neutrons or long-lived radioactive waste. Combined with the potential for direct energy conversion, this makes it a promising candidate for safe, carbon-free, baseload power generation.
🔹The plasma is a compact torus (“smoke ring”) of hot, dense ions and electrons confined in a linear cylindrical vacuum chamber by magnetic fields.
🔹Unlike a tokamak, where large external coils dominate confinement, an FRC’s plasma current generates much of its own confining magnetic field, reducing the need for massive external magnets and enabling a simpler, linear geometry.
🔹FRCs can, in principle, achieve up to ~100× more fusion power output than a tokamak of the same magnetic field and plasma volume because of their high-power density and geometry.
BEAM-DRIVEN STABILIZATION
🔹Historically, FRCs were unstable (wobble, slow down, and collapse).
🔹The solution is to continuously inject high energy neutral beams tangentially into the plasma. Once ionized, these “beam ions” orbit and drive a strong toroidal current that:
🔹Maintains rotation and pressure
🔹Suppresses instabilities
🔹Heats the plasma to fusion relevant temperatures.
