Dust particle charge in plasma with ion flow and electron depletion near plasma boundaries
(Physics of Plasmas, 2011-08-01)
The charge on micrometer-sized dust particles suspended in plasma above the powered electrode of radio-frequency discharges is studied. Using a self-consistent fluid model, the plasma profiles above the electrode are ...
Charging and Growth of Fractal Dust Grains
(IEEE Transactions on Plasma Science, 2008-02)
The structure and evolution of aggregate grains formed within a plasma environment are dependent on the charge acquired by the micron-sized dust grains during the coagulation process. The manner in which the charge is ...
Charged Grains In Saturn's F-Ring: Interaction With Saturn's Magnetic Field
(Advances in Space Research, 2004)
Saturn’s dynamic F-Ring still presents a challenge for understanding and explaining the kinematic processes that lead to the changing structure visible in our observations of this ring. This study examines the effect of ...
Digital Imaging and Analysis of Dusty Plasmas
(Advances in Space Research, 2004)
Dust particles immersed within a plasma environment, such as those found in planetary rings or cometary environments, will acquire an electric charge. If the ratio of interparticle potential energy to average kinetic energy ...
Dynamics of a Dust Crystal with Two Different Size Dust Species
(Advances in Space Research, 2006)
A self-consistent 3D model for a complex (dusty) plasma is used to study the effects of multiple-sized dust grains in a dust crystal. In addition to the interparticle forces, which interact through a Yukawa potential, the ...
The effect of dust charge variation, due to ion flow and electron depletion, on dust levitation
(AIP Conference Proceedings, 2011)
Using a fluid model, the plasma densities, electron temperature and ion Mach number in front of a powered electrode in different plasma discharges is computed. The dust charge is computed using OML theory for Maxwellian ...
Agglomeration of Dust Particles in the Lab
(AIP Conference Proceedings, 2011)
Dust aggregates are formed in a laboratory plasma as monodisperse spheres are accelerated in a self-excited dust density wave. The asymmetric charge on the aggregates causes them to rotate as they interact with the sheath ...
Comparison of Plasma Magnetic Field Interactions in a Static and Dynamic Plasma Facility
(Transactions of the Japan Society for Aeronautical and Space Sciences, Aerospace Technology Japan, 2016)
Magnetic fields are a principal/widespread/promising tool/instrument in space technology design for the use in advanced propulsion concepts, shielding from radiation or to aid thermal protection during the atmospheric ...
Electrical Conductivity of the Thermal Dusty Plasma under the Conditions of a Hybrid Plasma Environment Simulation Facility
(New Journal of Physcis, 2015-05-27)
We discuss the inductively heated plasma generator (IPG) facility in application to the generation of the thermal dusty plasma formed by the positively charged dust particles and the electrons emitted by them. We develop ...
Self-diffusion in two-dimensional quasi-magnetized rotating dusty plasmas
(Physical Review E, 2019-01-10)
The self-diffusion phenomenon in a two-dimensional dusty plasma at extremely strong (effective) magnetic fields is studied experimentally and by means of molecular dynamics simulations. In the experiment the high magnetic ...
