Dynamics of a Dust Crystal with Two Different Size Dust Species
(Advances in Space Research, 2006)
A self-consistent 3D model for a complex (dusty) plasma is used to study the effects of multiple-sized dust grains in a dust crystal. In addition to the interparticle forces, which interact through a Yukawa potential, the ...
Mode couplings and resonance instabilities in dust clusters
(Physical Review E, 2013-10-16)
The normal modes for three to seven particle two-dimensional (2D) dust clusters in a complex plasma are investigated using an N-body simulation. The ion wakefield downstream of each particle is shown to induce coupling ...
Vibrational Modes and Instabilities of a Dust Particle Pair in a Complex Plasma
(IEEE Transactions on Plasma Science, 2010-04-10)
Vibrational modes and instabilities of a dust-particle pair in a terrestrial aboratory complex plasma are investigated by employing an analytical method whereby the plasma wakefield induced by an external electric field ...
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 ...
Mode Couplings and Conversions for Horizontal Dust Particle Pairs in Complex Plasmas
(IEEE Transactions on Plasma Science, 2013-04)
The normal modes for horizontal dust particle pairs in a complex plasma are investigated using two methods, a numerical calculation and a molecular dynamics simulation. The ion wakefield downstream of each particle and the ...
Simple method to measure the interaction potential of dielectric grains in a dusty plasma
(Physics Review E, 2010-09)
A simple minimally perturbative method is introduced which provides the ability to experimentally measure both the radial confining potential and the interaction potential between two individual dust particles, levitated ...
Mode couplings and resonance instabilities in finite dust chains
(American Physical Society, 2015-05-08)
Employing a numerical simulation, the normal modes are investigated for finite, one-dimensional horizontal
dust chains in complex plasma. Mode couplings induced by the ion flow within the sheath are identified in the
mode ...
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 ...
Mode coupling and resonance instabilities in quasi-two-dimensional dust clusters in complex plasmas
(American Physical Society, 2014-09-16)
Small quasi-two-dimensional dust clusters consisting of three to eleven particles are formed in an argon plasma under varying rf power. Their normal modes are investigated through their mode spectra obtained from tracking ...
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 ...
