High-power and high-specific-impulse characteristics of Hall thrusters were experimentally studied. Input power and specific impulse reached above 5 kW and 3000 sec, respectively. As a result, the specific impulse and the thrust efficiency were 3202 sec and 61 %, respectively, with 2.8 kW. Discharge current oscillation also increased by raising discharge voltage.
Development of Hall thrusters for nano, small and low-power satellites below 100W is expected. In lowering Hall thruster power, the cylindrical-type Hall thruster is more advantage than conventional coaxial-type Hall thrusters. In this study, a very low power cylindrical Hall thruster was designed, and the thruster performance was measured. As a result, a stable operation was achieved even with 10W...
