Optimization of Cylindrical Hall Thrusters [PDF]
43rd AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2007 The cylindrical Hall thruster features high ionization efficiency, quiet operation, and ion acceleration in a large volume-to-surface ratio channel with performance comparable with the state-of-the-art annular Hall thrusters. These characteristics were demonstrated in low and medium power ranges.
