  • Interaction force in a vertical dust chain inside a glass box 

    Kong, J.; Qiao, K.; Matthews, L.S.; Hyde, T.W. (Physical Review E, 2014-07-31)
    Small number dust particle clusters can be used as probes for plasma diagnostics. The number of dust particles as well as cluster size and shape can be easily controlled employing a glass box placed within a Gaseous ...
  • Measurement of net electric charge and dipole moment of dust aggregates in a complex plasma 

    Yousefi, Raziyeh; Davis, Allen; Carmona-Reyes, Jorge; Matthews, Lorin; Hyde, Truell (Physical Review E, 2014-09-02)
    Understanding the agglomeration of dust particles in complex plasmas requires knowledge of basic properties such as the net electrostatic charge and dipole moment of the dust. In this study, dust aggregates are formed from ...
  • Mode coupling and resonance instabilities in quasi-two-dimensional dust clusters in complex plasmas 

    Qiao, Ke; Kong, J.; Carmona, J.; Matthews, L. S.; Hyde, T. W. (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 ...
  • Mode Couplings and Conversions for Horizontal Dust Particle Pairs in Complex Plasmas 

    Qiao, Ke; Kong, Jie; Zhang, Zhuanhao; Matthews, Lorin; Hyde, Truell (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 ...

    Qiao, K.; Kong, J.; Matthews, L.; Hyde, T. W. (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 ...
  • A New Inductively Driven Plasma Generator (IPG6)—Setup and Initial Experiments 

    Dropmann, Michael; Herdrich, Georg; Laufer, Rene; Puckert, Dominik; Fulge, Hannes; Fasoulas, Stefanos; Schmoke, Jimmy; Cook, Mike; Hyde, Truell W. (IEEE Transactions on Plasma Science, 2013-04)
    As part of the partnership between the Center for Astrophysics, Space Physics and Engineering Research (CASPER) at Baylor University and the Institute of Space Systems (IRS) at the University of Stuttgart, a new design for ...
  • One-dimensional vertical dust strings in a glass box 

    Kong, Jie; Hyde, Truell; Matthews, Lorin; Qiao, Ke; Zhang, Zhuanhao (Physical Review E, 2011-07-28)
    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 ...
  • Phase Transitions in a Dusty Plasma with Two Distinct Particle Sizes 

    Smith, Bernard; Hyde, Truell; Matthews, Lorin; Reay, Jerry; Cook, Mike; Schmoke, Jimmy (Advances in Space Research, 2008)
    In semiconductor manufacturing, contamination due to particulates significantly decreases the yield and quality of device fabrication, therefore increasing the cost of production. Dust particle clouds can be found in almost ...
  • Probing the sheath electric field using thermophoresis in dusty plasma 

    Land, Victor; Smith, Bernie; Matthews, Lorin; Hyde, Truell (IEEE Transactions on Plasma Science, 2010-04)
    A self-consistent dusty plasma fluid model has been extended to incorporate all the oble gases as the carrier gas. An analysis of void closure in complex plasma composed of these gases over a wide range of experimental ...
