A nominal 8-kW Hall thruster system was developed for high power spacecraft applications. This thruster is supported by a 1.3 cm hollow cathode. Performance was measured directly at conditions representative of the space environment, bringing the Technology Readiness Level (TRL) to 5. At nominal conditions, the thruster delivers half a Newton of thrust at 8-kW with a specific impulse of greater 1900 s. Deep throttling capabilities were demonstrated. Performance and throttling curves are presented. Data were taken with xenon, krypton, and iodine. Details of the thruster and system components are also presented.
