A tokamak (/ ˈ t oʊ k ə m æ k /; Russian: токамáк) is a device which uses a powerful magnetic field generated by external magnets to confine plasma in the shape of an axially symmetrical torus. [1] The tokamak is one of several types of magnetic confinement devices being developed to produce controlled thermonuclear fusion power.
The T-15 (or Tokamak-15) is a Russian (previously Soviet) nuclear fusion research reactor located at the Kurchatov Institute, which is based on the (Soviet-invented) tokamak design. [2] It was the first industrial prototype fusion reactor to use superconducting magnets to control the plasma . [ 3 ]
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 that gives it an overall shape similar to a donut , complete with a large hole in the middle.
Tokamak (Russian: токама́к, an abbreviation of the Russian words тороидальная камера в магнитных катушках, toroidal'naya kamera v magnitnykh katushkakh, toroidal chamber in magnetic coils (Tochamac), invented in the 1950s) In nuclear fusion, a toroidal apparatus in which plasma is contained by means ...
After developing the bomb, Sakharov and Tamm began work on the tokamak system in 1951. A tokamak (Russian: Токамáк) is a device that uses a powerful magnetic field to confine a hot plasma in the shape of a torus. The tokamak is one of several types of magnetic confinement devices being developed to produce controlled thermonuclear fusion ...
The tokamak became a topic of serious discussion in 1968, when the Soviets published new data showing them to be far better than any other fusion device. This generated significant skepticism among other researchers and it was some time before the PPPL was convinced to convert their Model C stellarator to the tokamak configuration.
Lev Andreyevich Artsimovich (Russian: Лев Андреевич Арцимович, February 25, 1909 – March 1, 1973), also transliterated Arzimowitsch, was a Soviet physicist known for his contributions to the Tokamak— a device that produces controlled thermonuclear fusion power.
Igor Nikolaevich Golovin (Russian: Игорь Николаевич Головин; 12 March 1913 – 15 April 1997) was a Russian physicist whose career was spent on the former Soviet program of nuclear weapons and nuclear fusion. He is known for coining the term Tokamak.
