  • Hartmann, Peter; Douglass, Angela; Carmona-Reyes, Jorge; Matthews, Lorin; Hyde, Truell; Kovacs, Aniko; Donko, Zoltan (Physical Review Letters, )
    We report a series of complex (dusty) plasma experiments, aimed at the study of the detailed time evolution of the recrystallization process following a rapid quench of a two-dimensional dust liquid. The experiments were ...
  • 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 ...
  • Douglass, Angela; Land, Victor; Matthews, Lorin; Hyde, Truell (Physics of Plasmas, )
    The charge on micrometer-sized dust particles suspended in plasma above the powered electrode of radio-frequency discharges is studied. Using a self-consistent fluid model, the plasma profiles above the electrode are ...
  • 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 ...
  • 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 ...
