A "dusty" or "complex" plasma is simply a plasma that contains charged, usually micron-sized particulates (dust grains). When suspended in the plasma, these charged dust particles fully interact with the ions and electrons in the plasma. In this way, the dust particles modify the properties of the plasma as well as introducing new, dust-driven plasma modes. |
Because the presence of charged dust in plasma is relevant to environments ranging from industrial plasma process devices to the space plasma environment to the edges of fusion energy experiments, the study of dusty plasmas has recently become one of the fastest growing areas of plasma physics.
At Auburn, we are performing experimental and computational studies of particle transport, wave properties, and dust grain charging in dusty plasmas. The centerpiece of the dusty plasma laboratory is a two-dimensional particle image velocimetry (PIV) diagnostic system.
