Ionization instabilities in partially magnetized plasmas

Plasma is a gas of charged particles which is the most common state of the matter in the visible universe. It is also widely used in laboratory and industry for numerous practical applications such as plasma processing devices, spacecraft thrusters, and future fusion reactors. Therefore physics of plasmas addresses a number of fundamental problems such as solar and space activity, solar dynamo, astrophysical jet as well as many applied technology problems. The objective of this project is to study and explain the mechanisms of turbulent low-frequency behavior of Hall effect thrusters, a class of plasma devices used for both electric propulsion in space and for satellite orbit keeping. One of the characteristics of Hall thruster is the presence of turbulence and structures that cause anomalous transport and greatly affect their efficiency. We will involve methods of analytical and computational analysis to address the nature of structures and learn how to control them. This research is not only of great practical importance but also addresses fundamental problems of plasma physics and plasma turbulence.
