The Field-Reversed Configuration (FRC)

MAGNETIC TOPOLOGY
The FRC has a very simple field topology because there is no toroidal field. It has a toroidal current ring embedded in a simple magnetic "mirror" (those fields entering at the left of the diagram and exiting to the right).

ADVANTAGES

• Compact.
• High power density.
• Natural power exhaust channel (direct energy
  conversion is possible).
• Low internal magnetic field (possible use of
  advanced fuels).
