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 ...
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 ...
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 ...
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 ...
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 ...
