Using Dust as Probes to Determine Sheath Extent and Structure
Angela Douglass, Victor Land, Ke Qiao +2
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 pr…
Slow plastic creep of 2D dusty plasma solids
Peter Hartmann, Anikó Zs. Kovács, Angela M. Douglass +3
We report complex plasma experiments, assisted by numerical simulations, providing an alternative qualitative link between the macroscopic response of polycrystalline solid matter…
Glow and dust in plasma boundaries
Victor Land, Angela Douglass, Ke Qiao +3
The sheath region is probed in different complex plasma experiments using dust particles in addition to measurement of the optical emission originating from the plasma. The local m…
Determination of the levitation limits of dust particles within the sheath in complex plasma experiments
Angela Douglass, Victor Land, Ke Qiao +2
Experiments are performed in which dust particles are levitated at varying heights above the powered electrode in a RF plasma discharge by changing the discharge power. The traject…
The effect of dust charge variation, due to ion flow and electron depletion, on dust levitation
Victor Land, Angela Douglass, Ke Qiao +2
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 c…
One-dimensional vertical dust strings in a glass box
Jie Kong, Truell Hyde, Lorin Matthews +3
The oscillation spectrum of a one-dimensional vertical dust string formed inside a glass box on top of the lower electrode in a GEC reference cell was studied. A mechanism for crea…
