tokamak |
Also found in: Wikipedia, Hutchinson | 0.02 sec. |
tokamakDevice used in nuclear-fusion research for magnetic confinement of plasma. It consists of a complex system of magnetic fields that confine the plasma of reactive charged particles in a hollow, doughnut-shaped container. The tokamak (an acronym from the Russian words for toroidal magnetic confinement) was developed in the mid-1960s by Soviet plasma physicists. It produces the highest plasma temperatures, densities, and confinement durations of any confinement device. tokamak [′täk·ə‚mak] (plasma physics) 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.

According to PPPL, "These computer systems provide real-time instrumentation, device monitoring and control, data acquisition and graphics display in support of round-the-clock operation of the Tokamak Fusion Test Reactor ( last December, using a magnetically confined mixture or equal parts deuterium and tritium, researchers at the Princeton University Plasma Physics laboratory and their collaborators achieve record outputs of fusion power at the Tokamak Fusion Test Reactor ( The experiments, conducted at the Tokamak Fusion Test Reactor, will continue through most of 1994. |
