Measurement of the ion drag force in a collisionless plasma with strong ion-grain coupling
نویسندگان
چکیده
The ion drag force acting on dust grains was measured experimentally in a low-pressure Ar plasma in the regime of strong ion-grain coupling. Argon ions were drifting in the axial ambipolar electric field naturally present in a hot-filament dc discharge plasma. Following the method of Hirt et al. Phys. Plasmas 11, 569

Particle in cell calculation of plasma force on a small grain in a non-uniform collisional sheath
The plasma force on grains of specified charge and height in a collisional DC plasma sheath are calculated using the multidimensional particle in cell code COPTIC. The background ion velocity distribution functions for the unperturbed sheath vary substantially with collisionality. The grain force is found to agree quite well with a combination of background electric field force plus ion drag fo...
متن کاملForces on a small grain in the nonlinear plasma wake of another.
The transverse force on a spherical charged grain lying in the plasma wake of another grain is analyzed to assess the importance of ion-drag perturbation, in addition to the wake-potential-gradient. The ion-drag perturbation is intrinsically one order smaller than the wake-potential force in the ratio of grain size (r(p)) to Debye length (λ(De)). So ion-drag perturbation is important only in no...
متن کاملOn non-linear excitation of voids in dusty plasmas
The void, which is a dust-free region inside the dust cloud in the plasma, results from a balance of the electrostatic force and the ion drag force on a dust particulate. The ion drag force having numerous forms, some of which are based on models whereas others are driven from first principles. To explain the generation of voids, Avinash et al. proposed a timedependent nonlinear model that desc...
متن کاملVortex motion of dust particles due to non-conservative ion drag force in a plasma
Vortex motion of the dust in a dusty plasma is shown to result because non-parallelism of the ion density gradient and the gradient of the magnitude of the ion ambipolar velocity cause the ion drag force on dust grains to be non-conservative. Dust grain poloidal vortices consistent with the model predictions are experimentally observed, and the vortices change character with imposed changes in ...
متن کاملRadiometric force in dusty plasmas.
It is shown that inhomogeneous heating of the dust grain by ion flow in a glow discharge results in a photophoresislike force. According to our estimations, this radiometric force can be comparably-valued with the ion-drag force under the conditions of microgravity dusty plasma experiments.
