Found inMcGraw-Hill dict. of sci. and tech. terms, c2003 (tokamak: A device for confining a plasma within a toroidal chamber, which produces plasma temperatures, densities, and confinement times greater than that of any other such device; confinement is effected by a very strong externally applied toroidal field, plus a weaker poloidal field produced by a toroidally directed plasma current, and this current causes ohmic heating of the plasma)
The Wordsworth dict. of sci. & tech., 1995 (tokamak (Phys.). Torus-shaped magnetic bottle, using an auxiliary magnetic field to achieve good plasma confinement for nuclear fusion; Tokamak (Nuc.Eng.). In fusion, a toroidal apparatus for containing plasma by means of two magnetic fields, (a) a strong toroidal magnetic field created by coils surrounding the vacuum chamber and (b) a weaker poloidal field created by an intense electric current through the plasma. Tokamak is an acronym of the Russian words meaning toroidal magnetic chamber)
