Agglomeration of Dust Particles in the Lab
(AIP Conference Proceedings, 2011)
Dust aggregates are formed in a laboratory plasma as monodisperse spheres are accelerated in a self-excited dust density wave. The asymmetric charge on the aggregates causes them to rotate as they interact with the sheath ...
Dipole-dipole interactions of charged magnetic grains
The interaction between dust grains is an important process in fields as diverse as planetesimal formation or the plasma processing of silicon wafers into computer chips. This interaction depends in large part on the ...
Vertical Interaction Between Dust Particles Confined in a Glass Box in a Complex Plasma
(IEEE Transactions on Plasma Science, 2013-04)
In this experiment, falling particle trajectories within and without a glass box placed on the lower electrode in a Gaseous Electronics Conference reference cell are recorded and analyzed, and the electrostatic forces ...
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 ...
Nonlinear response of vertical paired structure in complex plasma
(Plasma Physics and Controlled Fusion, 2019-03-21)
The effect of the ion wake downstream of grains immersed in a flowing plasma is observed experimentally through the apparent non-reciprocal grain–grain interactions. Here we extend amplitude-frequency response analysis to ...
