Plasma Table

A dust cloud of silicon micro-spheres that was illuminated by laser light scattering from the cloud is suspended in a plasma. The dust cloud is approximately 0.5 high and floats in a conical shape between the dust tray and an electrode as long as the plasma is maintained. Fundamental dust cloud properties and dynamics have applications from plasma processing to space plasmas.
