The safety factor, labeled q or q(r), is the ratio of the times a particular magnetic field line travels around a toroidal confinement area's "long way" (toroidally) to the "short way" (poloidally). The term "safety" refers to the resulting stability of the plasma; plasmas that rotate around the torus poloidally about the same number of times ...
A spherical tokamak is a type of fusion power device based on the tokamak principle. It is notable for its very narrow profile, or aspect ratio . A traditional tokamak has a toroidal confinement area that gives it an overall shape similar to a donut , complete with a large hole in the middle.
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] The tokamak is one of several types of magnetic confinement devices being developed to produce controlled thermonuclear fusion power.
The Experimental Advanced Superconducting Tokamak (EAST), also known as HT-7U (Hefei Tokamak 7 Upgrade), is an experimental superconducting tokamak magnetic fusion energy reactor in Hefei, China. Operated by the Hefei Institutes of Physical Science conducting its experiments for the Chinese Academy of Sciences , EAST began its operations in 2006.
As of 2023 the device is known as JT-60SA and is the largest operational superconducting tokamak in the world, [1] built and operated jointly by the European Union and Japan in Naka, Ibaraki Prefecture. [2] [3] SA stands for super advanced tokamak, including a D-shaped plasma cross-section, superconducting coils, and active feedback control.
