Residual Microparticle Charge Measured in a Spatio-Temporal Afterglow Plasma

The elementary interaction between dust particles and plasma, i.e. dusty or complex plasma physics, has been a widely researched topic for many years. A specific type of dusty plasma that has been of interest recently is a dusty afterglow plasma. The term afterglow is used to describe a (region of) plasma, in which the power source is removed and in which there is no (net) ionization. There are different types of afterglow plasmas: temporal afterglow plasmas, spatial afterglow plasmas, and combinations of the two. Dust interaction with temporal and spatial afterglow plasmas, specifically the charging of dust particles, has been investigated in many works. However, dusty spatio-temporal afterglow plasmas have remained far from fully explored.
