Abstract

A low power cylindrical Hall thruster (CHT) and fully cylindrical Hall thruster (FCHT) both demonstrated plume divergence reductions of approximately 25% by running a keeper discharge along with the anode discharge. Thruster anode efficiencies varied from approximately 15 to 35% over input powers from 70 to 220 W. A 2 A keeper discharge resulted in an approximately 20% increase in anode specific impulse for both thrusters, and the FCHT specific impulse was, on average, 13% higher than that of the CHT. Both thrusters exhibited mass utilization efficiencies greater than 100% due to generation of multi-charged ions. The quantity of channel erosion products in the plume correlated with that of multi-charged ions.
