Electromagnetic ion streaming instability

The Physics of Fluids, 1973
The instability of electromagnetic linearly polarized waves is discussed for a system composed of two identical counterstreaming ion beams in a uniform background of relatively stationary electrons.

Two-stream whistler instability

Plasma Physics, 1982
The excitation of whistlers in a system of two identical interpenetrating electron streams moving in opposite directions with the relative velocity of the order of their thermal velocity is considered. The quasilinear relaxation of the stream distribution function is shown to cause the build-up of a plateau on the distribution function over ...

Two-Streaming Cyclotron Instability

The Physics of Fluids, 1967
A new electrostatic instability of counterstreaming ions occurring at cyclotron frequency is exhibited and discussed. It is conjectured that this instability may provide the mechanism for the enhanced trapping of the injected ion beam in DCX-II. Stability criteria are developed and in the limit of high anisotropy of the ions and not-too-cold electrons,

The instability of inhomogeneous plasma streams

Plasma Physics, 1972
The instability of plane‐parallel plasma streams with a nonuniform velocity profile, both in the absence and in the presence of a longitudinal magnetic field, has been investigated. The results for plasma streams are compared with those of ideal conductive liquid flows.

Two-stream electrostatic instability

Proceedings of the IEEE, 1972
The variations of the maximum growth rate and the associated frequency of oscillation and the drift velocity with the change in the number density of the streaming electrons relative to that of the stationary electrons are discussed for the instability of the longitudinal plasma wave having its wave vector in the direction of the electron stream. It is

Two-Stream Electromagnetic Instability

Canadian Journal of Physics, 1973
The characteristics of the instability of an electromagnetic wave propagating obliquely to a double stream in a plasma are investigated. Instability is shown to exist for all directions of the stream. The direction normal to the wave vector is a singular case for which the unstable wave has a zero frequency of oscillation and a growth rate which ...

Inhomogeneous Two-Stream Instability

The Physics of Fluids, 1968
It is shown that the well-known two-stream instability can under certain conditions be stabilized by the introduction of a periodic stationary electrostatic potential which is produced by the particle beams themselves.
