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 allow the plasma to achieve the conditions ...

Tokamak. The reaction chamber of the DIII-D, an experimental tokamak fusion reactor operated by General Atomics in San Diego, which has been used in research since it was completed in the late 1980s. The characteristic torus-shaped chamber is clad with graphite to help withstand the extreme heat. A tokamak ( / ˈtoʊkəmæk /; Russian ...
The tokamak is an experimental machine designed to harness the energy of fusion. Inside a tokamak, the energy produced through the fusion of atoms is absorbed as heat in the walls of the vessel. Just like a conventional power plant, a fusion power plant will use this heat to produce steam and then electricity by way of turbines and generators.

The name ‘tokamak’ comes from a Russian acronym for "toroidal chamber with magnetic coils" (тороидальная камера с магнитными катушками). A tokamak is based around a doughnut-shaped vacuum chamber called a torus, within which gaseous hydrogen fuel is subjected to extreme heat and pressure until it becomes plasma, an electrically charged, hot gas. Pl...
A tokamak can sustain plasma currents with electric currents equal to the most powerful bolts of lightning, known as the mega-ampere levelThe JET tokamak in England managed a world record fusion power output of 16 megawatts in 1997The central solenoid used for the ITER tokamak will be the largest superconducting magnet ever built, producing a field of 13 tesla, which is equivalent to 280,000 times the magnetic field of the E...Is the Tokamak Safe?
The fusion process is deemed inherently safe and a range of additional safety measures are built into fusion power plant designs. Even a cataclysmic breach in a tokamak would only create very low levels of radioactivity outside of the plant enclosure.
How hot is a Tokamak?
The temperatures within a tokamak must reach 150 million °C to turn the gas into plasma and for the fusion reaction to take place. These high temperatures are ten times greater than the temperature found in the core of the Sun.
Can a Tokamak Explode?
The chamber in a modern tokamak, such as the ITER tokamak, typically contains less than one tenth of a gram of hydrogen fuel at any given moment. Should a disruption occur during a pulse the reaction immediately cools down and ends, meaning that a nuclear explosion at a tokamak like ITER is not possible.
A tokamak is an experimental device that creates a nuclear fusionreaction, which in turn produces energy to heat water and produce steam that drives turbines to generate electricity. Nuclear fusion has the potential to provide clean and near-limitless energy if the challenges of production can be overcome. These challenges include being able to cre...
