Influence of magnetic field and density on the streaming instability in magnetized pair plasmas

Abstract

The influence of magnetic field and density on the streaming instability in the electronpositron plasma with the moving ion fluid in a magnetic field is investigated. The analytic expressions of the growth rate and oscillating frequency of the streaming instability are obtained as functions of the cyclotron frequency, electron density, positron density, ion density, streaming velocity, and wave number. The variation of the growth rate and oscillating frequency of streaming instability due to the change of magnetic field and plasma parameters is discussed.

Unstable electrostatic surface waves in a turbulent plasma containing streaming ions: transverse truncation approach

“…Recently, the investigation of dense semi-classical or quantum plasmas has received a considerable attention since the dense degenerate plasma is found in modern science and technology such as nano-plasma, quantum-dot, and quantum-well, etc [22][23][24][25][26][27]. Moreover, the streaming instability has been of a great interest in plasmas since it is shown that the instability condition provides a useful information on the characteristics and properties of the plasma configurations with streaming components [28][29][30]. Hence, the investigation on the damping rate and the propagation of the surface waves propagating on the interface of the streaming dense semi-classical or quantum turbulent plasmas will be treated elsewhere since the companion of the quantum-mechanical and turbulence effects will produce unique phenomena on the damping rate of the surface wave in dense semi-classical or quantum turbulent plasmas.…”

Ion-driven instabilities of surface dust ion-acoustic waves in bounded plasma devices

“…Recently, for a semi-bounded dusty Lorentzian plasma containing streaming ions, the resonant instability growth rate was previously obtained [14]. If we take the thermalized electrons by letting the spectral index in the Lorentzian velocity distribution be infinity in [14], the result would be the same as equation (12).…”

“…It is well known that a beam of charged particles traveling through a plasma can be a source of instability due to the beam-wave interaction. This so-called streaming instability has attracted considerable interest in various plasmas because the instability condition has provided useful information on the physical characteristics and properties of plasma systems with streaming plasma components [8][9][10][11][12][13].…”

Hydrodynamic analysis of electrostatic counter‐streaming instability in a spin‐polarized electron–positron–ion plasma

“…[ 9 ] Later, various wave dispersions and instabilities were discussed in the cold, magnetized, and counter‐streaming electron–positron plasma, and the results were applied to an oscillating model for a pulsar magnetosphere. [ 10 ] Furthermore, how the magnetic field and positron concentration affect the growth rate of ion‐streaming instability in e‐p‐i magnetized plasma [ 11 ] was also investigated. The investigations of ion cyclotron streaming instability in e‐p‐i plasma was presented, and the growth rates of the instability for unidirectional streaming and counter‐streaming of electrons and positrons were compared.…”
