WebSafety factor. In tokamak research, the quantity q = 2π/ι is preferred (called the "safety factor"). In a circular tokamak, the equations of a field line on the flux surface are, … Web1.2 Safety factor Safety factor q is one of the key parameters describing the stability of the plasma in tokamak. The meaning of this dimensionless parameter is the number of toroidal turns it takes a magnetic fleld line to make a single full poloidal turn. For tokamak with large aspect ratio (R=a À 1) and circular cross{section, it is given ... In a toroidal fusion power reactor, the magnetic fields confining the plasma are formed in a helical shape, winding around the interior of the reactor. 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 … See more The key concept in magnetic confinement fusion is that ions and electrons in a plasma will rotate around magnetic lines of force. A simple way to confine a plasma would be to use a solenoid, a series of circular magnets … See more The effect of the helical field is to bend the path of a particle so it describes a loop around the cross section of the containment cylinder. At any given point in its orbit around the long axis of the toroid, the particle will be moving at an angle, θ. In the simple case, … See more Toroidal arrangements are a major class of magnetic fusion energy reactor designs. These are subject to a number of inherent instabilities that cause the plasma to exit the confinement … See more In the case of an axisymmetric system, which was common in earlier fusion devices, it is more common to use the safety factor, which is simply the inverse of the rotational transform: The safety factor is … See more • Troyon limit See more sighthound review magazine
