How to make large, void-free dust clusters in dusty
(IOP publishing, 2008-12-18)
Collections of micrometer-sized solid particles immersed in plasma
are used to mimic many systems from solid state and fluid physics, due to their
strong electrostatic interaction, their large inertia, and the fact that ...
Charging and coagulation of dust in protoplanetary environments
(Astrophysical Journal, 2012-01-01)
Combining a particle–particle, particle–cluster, and cluster–cluster agglomerationmodel with an aggregate charging model, the coagulation and charging of dust particles in plasma environments relevant for protoplanetary ...
Modeling Agglomeration of Dust Particles in Plasma
(AIP Conference Proceedings, 2011)
The charge on an aggregate immersed in a plasma environment distributes itself over the aggregate’s surface; this can be approximated theoretically by assuming a multipole distribution. The dipole-dipole (or higher order) ...
Charging of aggregate grains in astrophysical environments
(Astrophysical Journal, 2013-02-01)
The charging of dust grains in astrophysical environments has been investigated with the assumption that these grains are homogeneous spheres. However, there is evidence which suggests that many grains in astrophysical ...
Modelling of Voids in Complex Radio Frequency Plasmas
(WILEY-VCH, 2009-06-02)
In this paper hydrodynamic and kinetic approaches to model low pressure capacitively coupled complex radiofrequency
discharges are discussed and applied to discharges under microgravity. Experiments in the PKENefedov
reactor ...
Hydrodynamic and kinetic modelling of complex radio-frequency plasmas
(IOP publishing, 2009-09-18)
In this paper hydrodynamic and kinetic approaches to model low-pressure capacitively
coupled complex radio-frequency discharges are discussed and applied to discharges under
micro-gravity. Complex plasmas contain dust ...
Simulation of dust voids in complex plasmas
(IOP Publishing, 2008-11-04)
In dusty radio-frequency (RF) discharges under micro-gravity conditions often a
void is observed, a dust free region in the discharge center. This void is generated
by the drag of the positive ions pulled out of the ...
Determination of the levitation limits of dust particles within the sheath in complex plasma experiments
(Physics of Plasmas, 2012-01-23)
Experiments are performed in which dust particles are levitated at varying heights above the powered electrode in a radio frequency plasma discharge by changing the discharge power. The trajectories of particles dropped ...
Fluid modeling of void closure in microgravity noble gas complex plasmas
(Physics Review E, 2010-05-12)
A self-consistent dusty plasma fluid model has been extended to incorporate all the noble gases as the carrier gas. An analysis of void closure in complex plasma composed of these gases over a wide range of experimental ...
Glow and Dust in Plasma Boundaries
(IEEE Transactions on Plasma Science, 2013-04)
The sheath region is probed in different complex plasma experiments using dust particles in addition to the measurement of the optical emission originating from the plasma. The local maximum in the optical emission coincides ...
