Flute instability
WebMar 6, 2024 · The instability causes flute-like structures to appear on the surface of the plasma, and thus the instability is also known as the flute instability. [1] [2] The interchange instability is a key issue in the field of fusion energy, where magnetic fields are used to confine a plasma in a volume surrounded by the field. WebNov 29, 2024 · It is well known [ 1] that flute instability may arise in a dilute plasma in a non-uniform magnetic field. Flute oscillations become unstable in a fairly dense plasma, when r^ <, aR (here a and R are the characteristic scales of variation of the density and the magnetic fieldd =i , (T rt/47re 2n i)^ is the ion Debye radius.

Webin velocity space. The ion-acoustic instability is an example of an instability arising from such a velocity deviation, in this particular case in the form of electrons streaming with respect to ions. The Weibel instability is another example, which results from an anisotropic electron velocity distribution. These two illustrations are ... WebFeb 12, 2024 · Flute instability was observed at the plasma–field interface, which presents a salient kinetic feature rather than classical fluid instability. In the initial linear phase, the growth rate of the perturbation has good agreement with Large Larmor radius instability, which is larger than ion gyrofrequency. ...
