Breakthrough Long-life High-Isp Hall Thruster Technology With Auxiliary Gas Injection, Year 2
Project Description
Demonstrate auxiliary flow technique that lowers discharge oscillations and reduces pole erosion by >1 order of magnitude.\nDevelop physics-based numerical model of Hall thruster oscillations to inform the technology design.\nInject xenon gas near the exit plane of an existing (H6) MS Hall thruster to reduce oscillations during high-Isp operation.

Anticipated Benefits
Following JPL and NASA GRC's development of the 12.5 kW Hall Effect Rocket with Magnetic Shielding (HERMeS), which will be qualified for 23,000 hours of operation at Isp = 2000 - 3000 s, the next step forward for long-life Hall thrusters is naturally in high-Isp (\u2265 3000 s) operation.\nHigh-Isp Hall thrusters would enable deep space missions with higher payload fraction at reduced trip times compared to gridded ion engines, and at lower overall cost.
