Influence of size scaling and plasma-wall interaction on features of hall thruster microturbulence

Turbulence at length scales on the order of the electron Debye length has been shown to be a possible contributor to anomalous electron transport in the Hall thruster. Simulations

and coherent Thomson scattering experiments

have identified an azimuthal instability of megahertz frequency and millimeter wavelength which is associated with increased electron current.
