Direct measurements of two-dimensional velocity profiles in direct current glow discharge dusty plasmas

摘要

The letter details the first application of particle image velocimetry (PIV) techniques to dusty plasmas. Using PIV, two-dimensional velocity profiles are measured in dusty plasmas of silica particles that are suspended in the anode spot of an argon dc glow discharge plasma. This letter discusses the initial results of these studies and the potential applications of PIV techniques to dusty plasma studies. (C) 1999 American Institute of Physics. [S1070-664X(99)00507-8].
