Proton-cyclotron instability induced by the thermal anisotropy of minor ions
(Blackwell Publishing Ltd, 2002)
We study ion cyclotron instabilities due to the thermal anisotropy of minor heavy ions. Very large thermal anisotropics have been observed in O +5 ions in coronal holes [Cranmer, 2001], and as is well known, the thermal ...
Stochastic Ion Acceleration by the Ion-cyclotron Instability in a Growing Magnetic Field
(Institute of Physics Publishing, 2019)
© 2019 Institute of Physics Publishing. All rights reserved.Using 1D and 2D particle-in-cell simulations of a plasma with a growing magnetic field B, we show that ions can be stochastically accelerated by the ion-cyclotron ...
Effect of a large-amplitude circularly polarized wave on linear beam-plasma electromagnetic instabilities
(Blackwell Publishing Ltd, 2003)
In a previous paper, sufficiently large-amplitude and left-handed ‘‘pump waves’’
propagating parallel to the background magnetic field were shown to stabilize a
moderately dense beam in a proton plasma against the ...
Stabilization of linear ion beam right-hand polarized instabilities by nonlinear Alfvén/ion-cyclotron waves
(Blackwell Publishing Ltd, 2003)
It is shown that ion-beam plasma electromagnetic right-hand polarized instabilities can be stabilized by nonlinear left-hand polarized waves. This phenomenon constitutes a nonlinear saturation mechanism for right-hand ...
Ion cyclotron waves in space plasmas
(1996)
We study the linear and nonlinear properties of electromagnetic ion-cyclotron waves in the magnetosphere and the solar wind. In particular, we study parametric decays of large amplitude electromagnetic ion-cyclotron waves ...
Circularly polarized alfven and ion cyclotron waves in space plasmas
(1995)
The linear and nonlinear theory of circularly-polarized Alfvdn and ion-cyclotron waves in multicomponent plasmas is reviewed. It is shown that minor heavy- ion components play an important role in the dispersive properties ...
On the generation of totem pole emissions
(Blackwell Publishing Ltd, 2004)
Understanding of the generation of electron cyclotron harmonic waves by almost monoenergetic perpendicular ion beams contributes to the interpretation of the totem pole (TP) emissions observed at the Earth's magnetopause ...
Electrostatic instabilities triggered by finite amplitude Alfvén/ion-cyclotron waves and relative drifts among the ion components in the magnetosphere
(Blackwell Publishing Ltd, 2008)
Alfvén/ion-cyclotron waves have been observed in several regions of the magnetosphere. Parametric decays of finite amplitude Alfvén/ion- cyclotron waves in the presence of He+ ions and a mixed population of thermal and hot ...
Ion-beam-plasma electromagnetic instabilities
(Cambridge Univ Press, 2000)
It is well known that ion-beam-plasma interactions can destabilize right- and left-hand polarized electromagnetic waves. Owing to the fact that these instabilities have mostly been studied numerically by solving the ...
