Potential formulation of the dispersion relation for a uniform, magnetized plasma with stationary ions in terms of a vector phasor

The derivation of the helicon dispersion relation for a uniform plasma with stationary ions subject to a constant background magnetic field is reexamined in terms of the potential formulation of electrodynamics. Under the same conditions considered by the standard derivation, the nonlinear self-coupling between the perturbed electron flow and the potential it generates is addressed. The plane wave solution for general propagation vector is determined for all frequencies and expressed in terms of a vector phasor. The behavior of the solution as described in vacuum units depends upon the ratio o…

Wake effects of a stationary charged grain in streaming magnetized ions

A systematic numerical study of wake potential and ion density distribution of a single grain in streaming ions under the influence of the magnetic field applied along flow is presented. Strong magnetic field introduces ion focus depletion behind grain facilitating the entrance of electrons far away in the downstream towards the grain. It is shown that the magnetic field suppresses the amplitude of wake potential and modifies the ion density distribution substantially. The wake peak potential and position characteristics, and density distribution of plasma constituents in the presence of magne…

Characterisitics of the hall current surrounding a magnetized filamentary plasma

The hall current in the periphery of a filamentary plasma with the inwardly directed radial electric field, Er has been investigated experimentally by utilizing a TPD type dc discharge. When the cusp magnetic filed B$θ$ is applied perpendicular to the stationary background magnetic field Bz, the hall current by the ErxB$θ$ drift of electrons is induced in the periphery of the magnetized filamentary plasma.
