Nonlinear compressional electromagnetic ion-cyclotron wavepackets in space plasmas
The parametric coupling between large amplitude magnetic field-aligned circularly polarized electromagnetic ion-cyclotron (EMIC) waves and ponderomotively driven ion-acoustic perturbations in magnetized space plasmas is considered. A cubic nonlinear Schrödinger equation for the modulated EMIC wave envelope is derived, and then solved analytically. The modulated EMIC waves are found to be stable...
متن کاملCompressional-wave propagation in porous media saturated with two fluids
A theory of porous media with voids filled by two immiscible fluids should comply with Laplace’s law of capillary pressure at the pore level. For the convenience of practical use, it ideally should also involve only the generic elastic coefficients of the mineral grains and pore-filling fluids and avoid the use of “bulk” coefficients of the dry solid frame, whose measurement involves idealized ...
متن کاملObservation of wave-packet propagation in the ion cyclotron range of frequencies in a tokamak plasma
Experimental observation of wave-packet propagation in the ion cyclotron range of frequencies in a tokamak plasma is reported. Studies were carried out in the Caltech Research Tokamak [Phys. Fluids 23,614 ( 1980) ] in a pure hydrogen plasma and in a regime where fast-wave damping was sufficiently small to permit multiple toroidal transits of the wave packet. Waves were launched by exciting a sm...
متن کاملSolar off - limb line widths : Alfvén waves , ion - cyclotron waves , and preferential heating
Context. Alfvén waves and ion-cyclotron absorption of high-frequency waves are frequently brought into models devoted to coronal heating and fast solar-wind acceleration. Signatures of ion-cyclotron resonance have already been observed in situ in the solar wind (HELIOS spacecrafts) and, recently, in the upper corona (UVCS/SOHO remote-sensing results). Aims. We propose a method to constrain both...
متن کاملStudy of the Radio-frequency Driven Sheath in the Ion Cyclotron Slow Wave Antennas
The electrostatic Faraday screen(FS) is generally used to suppress the strong electrostatic interaction between the ICRF antenna and edge plasmas near the antenna. It is recognized that FS suppresses the electrostatic field parallel to the magnetic field(E//), and particle and heat fluxes into the antenna current strap effectively. Even with FS, however, impurity generation from FS is a severe ...
