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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
Using Dust as Probes to Determine Sheath Extent and Structure
(Journal of Plasma Physics, 2016-07)
Two in situ experimental methods are presented in which dust particles are used to determine the extent of the sheath and gain information about the time-averaged electric force profile within a radio frequency (RF) plasma ...
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 ...
Experimental and computational characterization of a modified GEC cell for dusty plasma experiments
(New Journal of Physics, 2009-06-12)
A self-consistent fluid model developed for simulations of microgravity
dusty plasma experiments has for the first time been used to model
asymmetric dusty plasma experiments in a modified Gaseous Electronics
Conference ...
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 ...
