Title: Plasma fluidized bed imaging and possible strong coupling effects

Abstract

A plasma fluidized bed was constructed to study the physics of fluidized plasmas. The plasma fluidized bed is a unique system involving contact of hydrodynamically suspended micron-sized (and larger) particles with the current-carrying portion of a plasma. These particles become negatively charged and, under certain conditions, could possibly form a strongly coupled fluidized plasma. Using laser light scattering measurements, we have imaged particles and calculated a coupling parameter showing what could be strongly coupled effects superimposed on the hydrodynamic behavior of the fluidized bed systems. This system may provide an ideal means to experimentally explore the properties and dynamics of strongly coupled plasmas subjected to hydrodynamic shear forces.
