Crossfield Magnetosonic Two Stream Instability

Canadian Journal of Physics, 1975
In this article, a detailed analysis was made on the plasma magnetosonic instabilites whose propagation is perpendicular to the magnetic field and whose two streams cross the magnetic field during the time of development of the instability.We have also studied the role of the magnetosonic instabilities in the structure of perpendicular shock waves ...

Non-symmetric two-stream instability

Journal of Plasma Physics, 1977
The recent Plum Brook—NASA experiments on counterstreaming plasma instabilities in which electric field emissions at frequencies [(n + ½) ±α]ωe (n = 1, 2, 3,…, 9, α < 0·5) have been observed, raised the theoretical problem of the non-symmetric two-stream instability.

Two-Stream Instability in Plasma

Journal of Applied Physics, 1967
The problem of two-stream instability in plasma is studied by specifying the importance of initial magnetic field associated with the motion of the charged particles and the boundary effects. In Part I the accurate initial steady state is studied when the streams of electrons and ions move with different uniform speeds in plasmas with plane and ...

Drifting oscillating two-stream instability

The Physics of Fluids, 1974
The theory of parametric excitation of plasma waves is applied to a plasma in which there is a static drift between electrons and ions. For appropriate values of drift speed and elevated electron-ion temperature ratio, there exists a solution of the dispersion relation and a threshold for instability at a frequency which is close to zero in the ...

Moon Formation via Streaming Instability

2022
&lt;ul&gt;&lt;li&gt;The Apollo lunar samples reveal that Earth and the Moon have strikingly similar isotopic ratios, suggesting that these bodies may share the same source materials. This leads to the &quot;standard&quot; giant impact hypothesis, suggesting the Moon formed from a partially vaporized disk that was generated by an

Two stream instability of quasiparticles

Physics Letters A, 1975
Abstract Two (or more) quasimonochromatic waves interacting in a nonlinear dispersive medium are shown to be unstable even if each wave is modulationally stable.

Generalized Stream Instabilities in Cold Plasmas

Physical Review, 1965
The classical double-stream theory for electrostatic instabilities in a cold plasma is generalized by a more complete treatment of the electrodynamics, whereby an analysis of electromagnetic instabilities is now afforded. Thus, consideration of wave propagation at arbitrary angles to the stream or drift motion leads to a rather involved sixth-degree ...

Electromagnetic Electron-Ion Streaming Instability

The Physics of Fluids, 1970
Instabilities produced by a current across a magnetic field and propagating obliquely to the field are studied in connection with the description of hydromagnetic shock waves. It is shown that there exist unstable waves of mixed polarization which can be described as coupled ion beam and whistler modes with frequencies given by ω≈k·u where u is the ...

Instability of Contra-Streaming Plasmas

The Physics of Fluids, 1960
The problem of instabilities in colliding ionized hydrogen beams, which has been treated by Kahn and Parker in the special case of zero temperature, is solved for the nonzero temperature case by taking Maxwell distributions for the equilibrium density functions.

Multi-Stream Instability in UMER

2018 IEEE Advanced Accelerator Concepts Workshop (AAC), 2018
Instability develops in a long space-charge dominated beam when it is allowed to coast in a storage ring without RF containment. The longitudinal space-charge forces in these intense beams cause it to expand axially, closing on itself and as a result wrapping the accelerator.
