Figure 1. Tokamak Exhaust Channels (IMAGE) American Physical Society Caption Cross-section of a tokamak plasma, with cylindrical symmetry axis at left side, showing a potential solution to the fusion power exhaust challenge: (1) top-bottom symmetric core plasma, defined by magnetic x-points and (2) specially designed, long-leg exhaust channels to dissipate the power via radiation, interaction with gas and a secondary magnetic x-point in the leg.
