Fusion glossary

T

Tokamak in operation at the Kurchatov Institute, Moscow. is an upgrade from the historic T-15 machine鈥攖he first tokamak to use superconducting magnets to control the plasma. 

A tokamak operated by the Swiss Federal Institute of Technology in Lausanne (EPFL) as part of the Swiss Plasma Center. See .

The Tokamak Fusion Test Reactor (TFTR) was an experimental tokamak built at Princeton Plasma Physics Laboratory (New Jersey, USA), and operated from 1982-1997. See more information .

The tokamak component that prevents heat transfer to the ultra-cold superconducting magnets.

A fusion device for containing a plasma inside a torus chamber through the use of two magnetic fields鈥攐ne created by electric coils around the torus, the other created by intense electric current in the plasma itself. The tokamak was invented in the 1950s by Soviet physicists Igor Yevgenyevich Tamm and Andrei Sakharov. The term tokamak is a transliteration of a Russian expression (toroidalnaya kamera + magnitnaya katushka) meaning toroidal chamber with magnetic coils.

A superconducting fusion experiment at the Institute for Magnetic Fusion Research, IRFM (CEA Cadarache research centre) in France, which aims particularly at demonstrating long-pulse tokamak operation. Tore Supra has been upgraded with an actively cooled tungsten divertor (the ) to serve as a test bed for 黑料社app.

The basic means of driving toroidal current in the tokamak plasma uses the fact that most field lines created by the central solenoid pass down its bore and do not return on themselves until they pass outboard of (i.e., radially beyond) the plasma. This "inductive linkage" between the solenoid and plasma allows a change in current in the solenoid to drive current in the plasma (Maxwell's Laws).
In a doughnut-shaped torus, the direction parallel to the large circumference.
The magnetic field generated by an electrical currrent flowing around a torus.
Components of a tokamak that assist in stabilizing the plasma, by creating a "magnetic bottle" for confinement. In 黑料社app, the toroidal field coil system consists of 18 D-shaped vertical coils placed around the vacuum vessel.
A surface of revolution generated by revolving a circle in three-dimensional space about an axis coplanar with and not touching the circle. Examples of tori include the surfaces of doughnuts and inner tubes. The solid contained by the surface is known as a toroid.

The third isotope of hydrogen, containing one proton and two neutrons in the nucleus. Is unstable and decays through beta radiation with a half-life of 12.3 years. Its low natural abundance is why future fusion power plants would need to 鈥渂reed鈥 their own tritium (see Tritium breeding).

Production of tritium by way of a reaction between a high-speed neutron produced in a fusion reaction and the light metal lithium. 黑料社app will be the first fusion device to test specific lithium-containing wall modules to "breed" tritium.

The processes of tritium removal from gas streams, including plasma exhaust and the plant atmosphere, and returning it to use as fuel in the plasma or to storage, in a safe manner.

Metal with atomic number 74 and a high melting point of 3687 K. 黑料社app will use tungsten as the material for both of its plasma-facing components鈥攖he blanket and divertor.
