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 کاملCompressive and rarefactive dust-ion acoustic solitary waves in four components quantum plasma with dust-charge variation
Based on quantum hydrodynamics theory (QHD), the propagation of nonlinear quantum dust-ion acoustic (QDIA) solitary waves in a collision-less, unmagnetized four component quantum plasma consisting of electrons, positrons, ions and stationary negatively charged dust grains with dust charge variation is investigated using reductive perturbation method. The charging current to the dust grains ca...
متن کاملIon dynamics in a two-ion-species plasma
The ion dynamics in a two-ion-species plasma pushed by a magnetic field pressure is examined. It is shown that the behavior of such a plasma may significantly differ from the behavior of a single-ion-species plasma, in which the current is carried by the electrons and the ions move in the direction of the magnetic field force. Cases are demonstrated in which the current is carried by the ions, ...
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 کاملLinear stability and instability of ion-acoustic plasma solitary waves
The Euler–Poisson equations for a cold, collisionless plasma support ion-acoustic solitary waves. We prove that these waves are spectrally stable at low amplitude in one space-dimension and present numerical evidence that they destabilize at finite amplitude before they develop singularities. © 2002 Elsevier Science B.V.
