What is tokamak explain?
A tokamak (/ˈtoʊkəmæk/; Russian: токамáк) is a device which uses a powerful magnetic field to confine 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 power.
What does tokamak mean in English?
: a toroidal device for producing controlled nuclear fusion that involves the confining and heating of a gaseous plasma by means of an electric current and magnetic field.
What is poloidal magnetic field?
The poloidal magnetic potential is a scalar quantity that contains information about the radial and latitudinal magnetic field vectors. To see the radial magnetic field, see The Solar Dynamo: Toroidal and Radial Magnetic Fields.
What is tokamak sometimes seen in the news?
The HL-2M Tokamak reactor is China’s largest and most advanced nuclear fusion experimental research device, and scientists hope that the device can potentially unlock a powerful clean energy source.
What does a tokamak look like?
Basic tokamak components include the toroidal field coils (in blue), the central solenoid (in green), and poloidal field coils (in grey). The total magnetic field (in black) around the torus confines the path of travel of the charged plasma particles.
What is a poloidal field?
poloidal field A magnetic field with radial and tangential components. The geomagnetic field detected at the Earth’s surface is of this form and contrasts with the unmeasurable toroidal field. A Dictionary of Earth Sciences.
What is toroidal field?
toroidal field A magnetic field with no radial components, e.g. where the magnetic lines of force lie on an electrically conducting spherical surface such as the surface of the Earth’s core. Such a field is not detectable at the Earth’s surface, in contrast to a poloidal field.
How many Tokamaks are there in the world?
An extensive list of current and historic tokamaks from around the world. (of which perhaps 50 are operating today). Please update your bookmarks to go to the domain www.tokamak.info which has remained unchanged even though the hosting location moved. After the move a lot of the links were broken but hopefully most are now fixed.
Where does the name tokamak ITER come from?
The term “tokamak” comes to us from a Russian acronym that stands for “toroidal chamber with magnetic coils” ( тороидальная камера с магнитными катушками ). To start the process, air and impurities are first evacuated from the vacuum chamber.
How is the energy produced in a tokamak used?
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. (Scroll down for more about the tokamak.)
How are particles energized in a tokamak fusion device?
Particles “energized” to such a degree can overcome their natural electromagnetic repulsion on collision to fuse, releasing huge amounts of energy. First developed by Soviet research in the late 1960s, the tokamak has been adopted around the world as the most promising configuration of magnetic fusion device.
