Mechanism(s) of the Anomalous Electron Current and Coherent Structures in Magnetized ExB Discharges
Abstract
This research develops theoretical models and numerical simulations tools to explain, predict, and control coherent structures and related anomalous electron current in the ExB devices such as Hall thrusters, magnetrons and Penning discharges. Four inter-related topics are addressed in this period: axial large scale ionization modes (breathing modes) in Hall thrusters; azimuthal modes, instabilities, and transport related to the electron-cyclotron drift instabilities in Hall thrusters; azimuthal instabilities and structures in cylindrical Penning discharge; and transonic accelerating flows formed by the Laval nozzle effect in the devices with magnetic nozzle and geometric apertures devices.
