Instabilities and transport in plasmas with EXB drift

Summary form only given. Electron and ion flows coupled with plasma and magnetic field inhomogeneity result in a number of instabilities in Hall thrusters and other systems with ExB drift, such as magnetrons and Penning discharges. The interaction of plasma density and magnetic field gradients, low-hybrid, collisional, and ionization driven instabilities are investigated within the reduced nonlinear fluid model taking into account the electron inertia and gyroviscosity. A new class of instabilities is uncovered due to anisotropic counter-streaming ion flows. The resulting turbulent state and anomalous electron transport are studied with nonlinear fluid simulations.
