Computational models for wave-particle interactions
Computer Physics Communications, 1986Abstract A 2-D finite-element evolution Fokker-Planck code, BACCHUS, is presented. The originally current-drive version and a more recent bounce-averaged version are discussed in some detail. A 1 1 2 - D quasi-linear code, RUNAWAY, is also described, especially to elucidate the major difficulties arising when the wave-particle interaction ...

Wave–particle interactions in plasmas
Plasma Physics and Controlled Fusion, 2006An overview of the interactions between waves and particles in plasmas is given. Interest is focused on cases where special particle populations, like energetic particle tails, interact with waves. The two basic, but inter-related, mechanisms through which waves and particles can exchange energy, resonance and stochastization are briefly illustrated ...

Linear Wave-Particle Interactions
1998Abstract Collisionless absorption of h.f. power is a remarkable property of hot plasmas, and it is of great theoretical interest to understand how it occurs. It also has practical importance, since the possibility of selective dissipation and thermalisation of h.f. waves with the appropriate frequency, phase velocity, and polarization is

Gyroresonant Wave-Particle Interactions
1972This review will be restricted to gyroresonant interactions. The basic processes of these interactions are discussed in the frame of the quasi-linear theory. Frequencies of interaction, anisotropy of the particle distribution function, and amplification and diffusion coefficients are computed for different types of interaction and different regions of ...

Wave-particle interactions in hot plasmas
AIP Conference Proceedings, 2006This overview talk focuses on the populations of particles which are transmitted through the nearly perpendicular termination shock from the solar wind to the heliosheath, and how they relax and excite waves in the heliosheath. The transmission process probably involves direct transmission of the very cold solar wind core.

Wave–Particle and Wave–Wave Interactions
2012In Chap. 3 we have discussed how plasma responds to an external (weak) electromagnetic perturbation, which results in a specific wave dispersion and damping. This damping is linear, i.e., proportional to the wave amplitude and there is no change in the plasma distribution function other than small oscillations proportional to the wave amplitude ...

Wave Particle Interaction — Some Laboratory Observations
1974Electrostatic waves are both a sign of, and intimately bound up with, significant changes in the particle velocity distribution in natural as well as laboratory plasmas. It has been known from some years of laboratory study that collisionless plasmas exhibit an abundance of electrostatic (k ∥ E) noise, or ‘microinstabilities’, in a very wide variety of

Magnetospheric Dynamics and Wave-Particle Interactions
1976It has been demonstrated that two general classes of wave-particle interactions are of great importance for magnetospheric dynamics. Electromagnetic and electrostatic plasma instabilities give rise to relatively narrow-banded spontaneous emissions (e.g.

Ac Fields and Wave Particle Interactions
1970Several new experiments provide detailed information about electrostatic and electromagnetic plasma waves in the outer magnetosphere, magnetosheath, and solar wind. Dipole antennas now commonly detect the electric components of whistler mode chorus and triggered emissions near 20 to 50 % of the local or equatorial gyrofrequency, and purely ...

Momentum transport by wave–particle interaction
Plasma Physics and Controlled Fusion, 2011Energy and momentum can be transported across the plasma by waves emitted at one place and absorbed at another. Exchange of momentum and energy between the particles and the waves change the drift orbits, which may give rise to a non-ambipolar particle transport.
