Tokamak - Wikipedia
网页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]
DOE Explains...Tokamaks | Department of Energy
网页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.
Tokamak - ITER
网页What is a TOKAMAK? Power plants everywhere generate electricity by converting mechanical power such as the rotation of a turbine into electrical power. In a coal-fired steam station, the combustion of coal turns water into steam and the steam in turn drives turbine generators to produce electricity.

Tokamak | Fusion Reactor, Plasma Confinement & Magnetic Field
网页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 Compact Fusion Reactor Barely 3 Feet Across Has Hit a Huge …
网页2023年6月1日 · Ions inside a compact fusion reactor barely a meter (less than 3 feet) across have been heated to the magic figure of 100 million degrees Celsius (some 180 million degrees Fahrenheit) for the first time in a monumental step towards making nuclear fusion energy a practical reality.
JT-60SA is now the largest operating tokamak: What does that …
网页2023年11月6日 · Operators of JT-60SA—a joint international fusion experiment being built by Japan and Europe in Naka, Japan—achieved the first tokamak plasma in the machine in late October, making it the world’s largest operational tokamak.
ITER Tokamak: World's Largest Fusion Reactor Begins Assembly
网页2020年7月28日 · The fusion reactor has millions of individual parts that will eventually form the world's largest tokamak, a plasma reactor where extremely hot, charged plasma creates the conditions necessary...
ITER - the way to new energy
网页2024年9月16日 · ITER is the world’s largest fusion experiment. Thirty-five nations are collaborating to build and operate the ITER Tokamak, the most complex machine ever designed, to prove that fusion is a viable source of large-scale, safe, and environmentally friendly energy for the planet.
Fusion’s New Magnetic Era: Unveiling the Secrets of Tokamak …
网页2024年1月13日 · A tokamak uses magnetic fields to confine plasma and reach the high temperatures necessary to produce nuclear fusion reactions. In some tokamak plasmas, confinement in a particular part of the plasma called the pedestal (the plasma edge) can allow large pressure gradients to form.
