Abstract

The formation of a small-scale plasma density depletion region extended along the ambient magnetic field and caused by the nonlinear interaction of the upper-hybrid plasma waves with a magnetoplasma has been observed under laboratory conditions modeling the ionospheric heating experiments. Plasma waves are trapped inside the depletion due to their specific dispersion properties. The threshold of the nonlinear wave trapping significantly increases in the vicinity of the harmonics of the electron gyrofrequency.

Nonlinear trapping and self-guiding of magnetized Langmuir waves due to thermal plasma filamentation

Nazarov, Vladimir V. ; Starodubtsev, Mikhail V. ; Kostrov, Alexander V. - Physics of Plasmas

Nonlinear interaction of Langmuir waves with a laboratory magnetoplasma has been studied under the conditions relevant to the ionospheric heating experiments. Self-guiding of magnetized Langmuir waves is observed at critical plasma density ({omega}={omega}{sub p}): Langmuir waves are trapped inside a narrow, magnetic-field-aligned plasma density depletion region, which is formed by trapped waves due to thermal plasma nonlinearity, i.e., due to local plasma heating and consequent thermodiffusion. Magnetized Langmuir waves are trapped inside the depletion region through their specific dispersion properties; this fact has been shown using the kinetically modified dispersion relation. The threshold of the nonlinear wave trapping exhibits significantmore »« less

Nonlinear charge-density waves in a bounded magnetized plasma

Lukomskii, V.P. - Sov. J. Plasma Phys. (Engl. Transl.); (United States)

The propagation of slightly nonlinear electron-density waves in a waveguide filled with a magnetized plasma is analyzed. It is assumed that the nonlinearity, the dispersion, and the dissipation are slight. Then the original nonlinear system of Vlasov--Poisson equations is reduced to a system of evolutionary equations of the Korteweg--de Vries type for the amplitudes of the waveguide modes. This system has a nonlocal term describing collisionless damping. In the case in which there is no mode degeneracy it is found that for only certain of these modes does a finite initial perturbation evolve to Korteweg--de Vries solitons. The conditions formore »« less
Laboratory study of anti-Stokes Langmuir waves in a magnetized plasma

Riddolls, R.J. ; Lee, M.C. ; Moriarty, D.T. ; ...

Anti-Stokes Langmuir waves were observed in the ionospheric plasma heating experiments at Arecibo, Puerto Rico. They are referred to as frequency upshifted Langmuir waves excited by injected high power HF waves. The frequency shifts are found to be inversely proportional to the HF pump wave frequencies, and of the magnitudes of the lower hybrid wave frequencies in the ionosphere. Kuo and Lee suggest that these anti-Stokes Langmuir waves are caused by the nonlinear scattering of HF wave-produced Langmuir waves off lightning-induced lower hybrid waves. Laboratory experiments with a large toroidal plasma machine known as the Versatile Toroidal Facility (VTF) havemore »« less
Depletion kinetics in the photobleaching trapping reaction inside a flat microchannel

Park, Sung Hyun ; Peng, Hailin ; Kopelman, Raoul ; ... - Physical Review. E, Statistical Physics, Plasmas, Fluids, and Related Interdisciplinary Topics

The diffusion-limited kinetics of the growth of a depletion zone around a static point trap in a thin, long channel geometry was studied using a laser photobleaching experiment of fluorescein dye inside a flat rectangular capillary. The dynamics of the depletion zone was monitored by the {theta} distance, defined as the distance from the trap to the point where the reactant concentration has been locally depleted to the specified survival fraction ({theta}) of its initial bulk value. A dimensional crossover from two dimensions to one dimension, due to the finite width of the reaction zone, was observed. We define amore »« less

Decay instability of circularly polarized waves into circularly polarized and Langmuir waves in a magnetized plasma

Lee, K.F. - J. Plasma Phys., v. 11, pp. 99-109

A study was made of a parametric instability in a magnetized plasma in which an electromagnetic pump wave of either right- or left-hand circular polarization decayed into a Langmuir wave and another circularly polarized wave, all with wave vectors colinear with the external magnetic field. The analysis was based on a multiple-time- scale perturbation expansion of the fluid equations, incorporating the effects of temperature, collisions, and the spatial variation of the pump wave. The threshold values of the pump field intensity required for instability and the growth rates above threshold were calculated. (auth)
