A tokamak (/ ˈtoʊkəmæk /; Russian: токамáк) is a machine [1] which uses a powerful magnetic field generated by external magnets to confine plasma in the shape of an axially symmetrical torus. [2] The tokamak is the leading candidate of magnetic confinement fusion designs being developed to produce controlled thermonuclear fusion power. [3] Tokamaks use a combination of a central ...
The FES program focuses on tokamaks because of the concept’s excellent ability to confine plasma, a feature necessary to sustain fusion reactions and realize fusion energy production.
Since Lev Artsimovich’s lecture in 1968, where he presented a successful reaching of temperature of 10 million kelvin in a T-3 tokamak, the tokamak principle has been perceived as a promising way to thermonuclear fusion. Rapid expansion of those experimental devices started all over the world and, to date, over fifty tokamaks have been built. A lot of them have been rebuilt and upgraded so ...
Formulated in the 1950s by Russian scientists First tokamak, T-1, operated in 1958 Tokamaks confine with an externally produced toroidal field and a plasma current produced poloidal field TOKAMAK is a Russian acronym: “Toroidal Chamber with Magnetic Coils” Leading magnetic confinement concept in terms of number of facilities and funding
The most common fusion reactors of that kind are tokamaks and stellarators. Currently, these are the most promising concepts for future fusion energy plants. Both reactor types make use of the fact that charged particles react to magnetic forces. Strong magnets in the reactors keep the ions confined.
A tokamak is a machine that confines a plasma using magnetic fields in a donut shape that scientists call a torus. Fusion energy scientists believe that tokamaks are the leading plasma confinement concept for future fusion power plants. In a tokamak, magnetic field coils confine plasma particles to ...
