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]

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.

Nov 16, 2024 · A tokamak is a device designed to hold plasma so we can bend it to our will, which ultimately is to replicate the fusion that takes place at the core of stars. On Earth, a plasma would...

The tokamak is an experimental machine designed to harness the energy of fusion; inside a tokamak, a fusion plasma is created and confined by strong magnetic fields. The energy produced through the fusion of atoms in the plasma is absorbed as heat in the walls of the vessel.

Dec 21, 2024 · A tokamak is a device designed to harness nuclear fusion, the reaction that powers the sun and all the stars. In a tokamak, magnetic field coils confine plasma to achieve the required conditions for fusion on the Earth.

Jan 10, 2025 · Researchers are closing in on the potential of nuclear fusion, the process that powers the stars, as a clean and inexhaustible energy source. At the heart of this effort is the tokamak reactor design, which uses magnetic fields to confine plasma and maintain the necessary conditions for fusion. A

Jan 30, 2021 · 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.

The word “tokamak” is of Russian origin and is an acronym for “TOroidalnaja KAmera i MAgnitnyje Katushki” — toroidal chamber and magnetic coils. It uses a magnetic cage in the shape of a torus (very much the same as the shape of a donut) created by magnetic coils.

Jan 27, 2025 · 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.

A tokamak is a type of thermonuclear reactor that uses magnetic confinement and currently represents one of the most advanced technologies for mastering thermonuclear fusion. The word “tokamak” itself is of Russian origin and is an abbreviation of four words aptly characterizing this type of device — toroidal chamber and magnetic coils.
