Ion-wake Field inside a Glass Box
(Physical Review E, 2016-09)
The confinement provided by a glass box is proving ideal for the formation of vertically aligned structures and a convenient method for controlling the number of dust particles comprising these dust structures as well as ...
Mapping of force field in a capacitively driven rf plasma discharge
(Journal of Plasma Physics, 2016-07)
In this paper a method is described that allows mapping of the forces acting on dust particles in a GEC reference cell. Monodisperse particles are dropped into the plasma environment and their trajectories are tracked using ...
Temperature Measurements of a Dust Particle
(Journal of Plasma Physics, 2016-09)
The thermal motion of a dust particle levitated in a plasma chamber is similar to that described by Brownian motion in many ways. The primary difference between a dust particle in a plasma system and a free Brownian particle ...
Multipole Expansions of Aggregate Charge: How Far to Go?
(IEEE Transactions on Plasma Science, 2016-04)
Aggregates immersed in a plasma or radiative environment will have charge distributed over their extended surface. Previous studies have modeled the aggregate charge using the monopole and dipole terms of a multipole ...
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 ...
