Planar double layers in magnetized plasmas: Fine structures and their consequences

Self-Excited Irregular Oscillation of Positively Charged Fine-Particles in Magnetized Double Plasmas

We have investigated behaviors of positively-charged fine particles in a cross-sheath between magnetized double plasmas with different potentials separated vertically by the horizontal magnetic field. In the sheath the charges on the particles become positive, because ion current flowing from a lower high-potential plasma surpasses electron current coming across the magnetic filed from an upper...

Propagating double layers in electronegative plasmas

Double layers have been observed to propagate from the source region to the diffusion chamber of a helicon-type reactor filled up with a low-pressure mixture of Ar/SF6 N. Plihon et al., J. Appl. Phys. 98, 023306 2005 . In the present paper the most significant and new experimental results are reported. A fully self-consistent hybrid model in which the electron energy distribution function, the ...

Dust in Magnetized Plasmas

Overview of recent progress in studies of magnetized dusty plasmas is presented. Dust dynamic under the influence of an applied magnetic field in various types of discharges and conditions (including dust dynamic in the magnetized plasma sheath) is examined. The various dust driven mechanisms in magnetized plasma are considered and comparison experimental and theoretical data is performed. Infl...

Ion acoustic waves and double-layers in electronegative expanding plasmas

Vortex interactions in magnetized plasmas

Current-vortex filament solutions to the twofluid plasma equations that describe drift-Alfvén waves are presented. Such filament systems are Hamiltonian. Integrable three and four filament systems are discussed in some detail. A wide variety of orbit topologies exists in the plasma case. Special attention is paid to collapses where all filaments contract to a single point. The differences and e...
