  • Douglass, Angela; Land, Victor; Qiao, Ke; Matthews, Lorin; Hyde, Truell (Physics of Plasmas, )
    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 ...
  • Land, Victor; Douglass, Angela; Qiao, Ke; Matthews, Lorin; Hyd, Truell (AIP Conference Proceedings, )
    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 ...
  • Land, Victor; Douglass, Angela; Qiao, Ke; Zhang, Zhuanhao; Matthews, Lorin; Hyde, Truell W. (IEEE Transactions on Plasma Science, )
    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 ...
  • Qiao, Ke; Kong, Jie; Zhang, Zhuanhao; Matthews, Lorin; Hyde, Truell (IEEE Transactions on Plasma Science, )
    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 ...
  • Kong, Jie; Hyde, Truell; Matthews, Lorin; Qiao, Ke; Zhang, Zhuanhao (Physical Review E, )
    The oscillation spectrum of a one-dimensional vertical dust string formed inside a glass box on top of the lower electrode in a gaseous electronics conference (GEC) reference cell was studied. A mechanism for creating a ...
  • Zhang, Zhuanhao; Qiao, Ke; Kong, Jie; Matthews, Lorin; Hyde, Truell (Physics Review E, )
    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 ...
  • Kong, Jie; Qiao, Ke; Carmona-Reyes, Jorge; Douglass, Angela; Zhang, Zhuanhao; Matthews, Lorin; Hyde, Truell (IEEE Transactions on Plasma Science, )
    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 ...
