The work resulted in a A generalization of the classical anode depletion theory of onset to conditions below onset, giving insights as to anode drops and flow rearrangements b Analytical results describing the current concentration at cathode roots due to the Hall effect, and also the axial voltage distribution in a segmented thruster with suppressed axial current c Completion of our study on local plasma stability, with the conclusion that damping, mostly due to heat conduction makes is unlikely that onset can be due to a local instability. Work was initiated on a theory of flow in contoured channels. Keywords Magnetoplasma dynamic thrusters Electric propulsion.
