Excitation of electrostatic ion-cyclotron waves by an ion beam in a two-ion component plasma
An ion beam propagating through a magnetized plasma cylinder containing electrons, light positive potassium ions K+ , and heavy positive cesium ions Cs+ drives electrostatic ion cyclotron EIC waves to instability via Cerenkov interaction. Two EIC wave modes are present, the K+ and Cs+ modes. The unstable wave frequencies and the growth rate of both the light positive ion and heavy positive ion ...
متن کاملCoronal ion-cyclotron beam instabilities within the multi-fluid description
Context. Spectroscopic observations and theoretical models suggest resonant wave-particle interactions, involving high-frequency ion-cyclotron waves, as the principal mechanism for heating and accelerating ions in the open coronal holes. However, the mechanism responsible for the generation of the ion-cyclotron waves remains unclear. One possible scenario is that ion beams originating from smal...
متن کاملElectrostatic Ion-cyclotron Waves Driven by Parallel Velocity Shear
Using a fluid treatment, it is shown that electrostatic waves with angular frequencies ~ ωci (ion cyclotron frequency) propagating at large angles to the ambient magnetic field can be excited in a magnetized plasma by perpendicular shear in the magnetic field aligned plasma flow. The role of density gradients in determining the stability of sheardriven EIC modes is also considered. PACS numbers...
متن کاملSpiky parallel electrostatic ion cyclotron and ion acoustic waves
One of the interesting observations from the FAST satellite is the detection of strong spiky waveforms in the parallel electric field in association with ion cyclotron oscillations in the perpendicular electric fields. We report here an analytical model of the coupled nonlinear ion cyclotron and ion-acoustic waves, which could explain the observations. Using the fluid equations for the plasma c...
متن کاملElectrostatic Ion - Cyclotron Waves in a Two - Ion Component Plasma
The excitation of electrostatic ion-cyclotron (EIC) waves is studied in a single-ended Q machine in a two-ion-component plasma (Cs+ and K+). Over a large range of relative concentrations of Cs+ and K+ ions, two modes are excited with frequencies w , z Q,,, and w2 t QK+, where the Q's are the respective cyclotron frequencies. The results are discussed in terms of a fluid theory of electrostatic ...
