| Abstract: | The Nuclear-Electric Xenon Ion Systems (NEXIS) thruster was designed to produce ≥70% efficiency at ISPs in excess of 6500 sec and total power levels in excess of 15 kW. In order to achieve this performance, the truster requires a large area plasma generator capable of high propellant utilization efficiency and low discharge loss while producing a very flat, uniform beam profile. Fortunately, larger thrusters can be made more uniform and efficient due to the higher volume to surface ratio, provided that the magnetic cusp confimement is designed properly and the truster lenght to diameter ratio is adequate. This paper describes the dischage chamber performance of the NEXIS "Laboratory Model" (LM) thruster. |
