Plasma Physics Seminar
“Dusty Plasma Experiments Under Microgravity Conditions” by Bin Liu, Ph.D., Department of Physics & Astronomy, The University of Iowa
Abstract: A dusty plasma contains micron-sized dust particles immersed in a gas plasma. The dust particles are negatively charged so that they repel one another, exhibiting oscillations such as dust acoustic waves. In this talk, flight experiments from European Space Agency ESA’s PK-4 instrument on board the International Space Station (ISS) will be described. We will also present our analysis of the flight data from early missions of the PK-4, including waves and particle velocity distribution functions.
