Abstract :
Transport of electrons across magnetic field lines in a Hall thruster is driven by factors such as collisions with background heavy particles, plasma turbulence, and wall effects. In this paper, we analyze the influence of secondary electron emission and electron scattering with thruster walls on cross-field diffusion in cylindrical Hall thrusters.
