Electrostatic 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 ...
متن کاملNonlinear Magnetosonic Waves in a Multi-ion-species Plasma
Magnetosonic waves are intensively studied due to their importance in space plasmas and also in fusion plasmas where they are used in particle acceleration and heating experiments. In the present paper we investigate the magnetosonic waves propagating in a multi-ionspecies plasma perpendicular to an external magnetic field. Due to the presence of several ion species, this mode splits into two b...
متن کاملExcitation 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 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 کاملInstability of higher harmonic electrostatic ion cyclotron waves in a negative ion plasma
We present a kinetic theory analysis of the electrostatic ion cyclotron (EIC) instability in a plasma containing positive ions, electrons, and negative ions that are much more massive than the positive ions. Conditions are investigated for exciting the fundamental and the higher harmonic EIC waves associated with each ion species. We find that as the concentration of heavy negative ions increas...
