Flute instability
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 ...

WebNon-MHD rfects in cur~alure driven flute instability 1187 p(dV/dt) = -divp+(l/c)[J,B], E+(l/c)[V,B] =O that should he supplemented by the continuity equation for the perturbed current div J' = 0.Integrating the continuity equation with a weight of ds/B along a field line and taking into account that at the isolated end walls Ji = 0, one obtains:
WebThe increase in fluctuations for the half-magnetic field experiments is expected due to the high frequency fields increasing the plasma temperature which increases the instability growth rate. The decrease in fluctuations for the nominal magnetic field experiments must be explained by a stabilizing mechanism. WebA low-frequency flute instability in a collisionless plasma flowing along a curved magnetic field has been observed to localize in regions of bad curvature (delB/sup 2/del>0). The …
WebNov 3, 2015 · The flute instability was identified by the measurements of the fluctuations in the ion saturation currents and floating potential. The direction of magnetic field strength gradient is the same as that of density gradient in M-ICP-A which makes it more susceptible to the occurrence of flute instability. Thus the density is higher in M-ICP-A ...
