A spherical tokamak is a type of fusion power device based on the tokamak principle. It is notable for its very narrow profile, or aspect ratio. A traditional tokamak has a toroidal confinement area t
A plasma in the MAST reactor. Note the almost spherical shape of the outside edge of the plasma. The high elongation is also evident, notably the filaments extending off the top and bottom near the central conductor.
