Stability Limits for Longitudinal Waves In Ion Beam-Plasma Interaction

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 ...

Nonlinear beam generated plasma waves as a source for enhanced plasma and ion acoustic lines

Linear 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.

Plasma Neutralization Models for Intense Ion Beam Transport in Plasma

Plasma neutralization of an intense ion pulse is of interest for many applications, including plasma lenses, heavy ion fusion, cosmic ray propagation, etc. An analytical electron fluid model has been developed based on the assumption of long charge bunches (lb>>rb). Theoretical predictions are compared with the results of calculations utilizing a particle-in-cell (PIC) code. The cold electron f...

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 ...
