Flute instability
WebThe stability of a plasma is an important consideration in the study of plasma physics. When a system containing a plasma is at equilibrium, it is possible for certain parts of the plasma to be disturbed by small perturbative forces acting on it. The stability of the system determines if the perturbations will grow, oscillate, or be damped out. 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 ...

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. WebMay 25, 2024 · Plasma Physics provides an essential introduction to the subject. A gas that is significantly ionized, usually by heating or photons, a plasma is composed of electrons and ions and sometimes has an embedded or confining magnetic field. Plasmas play a major role in many contemporary applications, phenomena, and fields, including …
