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

Webin tokamaks on the safety factor q.Petty et al. have found that in the DIII-D tokamak, both the ion and electron thermal diffusivities increase almost linearly with the safety factor q[1]. In gyro-fluid simulations of tokamak transport due to the ion temperature gradient (ITG) mode, the relationship χi∝qhas also been observed [2]. Webby operation with a safety factor q > 1 throughout the plasma. The basic characteristics in such scenario correspond to conditions of weakly reversed core magnetic shear with minimum value of qmin above unity [1]. However, in tokamaks like MAST, the discharges evolve such that WebAug 11, 2024 · Tokamaks, which are one of the most promising approaches to energy generation from nuclear fusion, are toroidal devices confining a very hot ionized gas, i.e. … forward nutrition
