The physics of magnetic shielding in Hall thrusters were validated through laboratory
experiments demonstrating essentially erosionless, high-performance operation. The …

NASA and the commercial aerospace industry have spent the last 40 years developing,
testing, and flying barium-oxide impregnated dispenser cathodes in ion thrusters, Hall …

Neutral flow dynamics in Hall thrusters are not often regarded as a critical aspect that
controls thruster operation and discharge channel physics. This dissertation, combined with …

LECTRON transport and channel erosion are two major technical challenges that have
persisted since the invention of the Hall thruster over fifty years ago. The first relates to the …

We describe an overview of the design process and acceptance testing of the magnetically
shielded H9, a 9-kW class Hall thruster developed by the Jet Propulsion Laboratory in …

INTEREST in Hall thruster research and development has increased significantly in the
United States over the past 20 years. Hall thrusters offer several system advantages over ion …

Magnetically shielded miniature (MaSMi) is a low power (≤ 1 kW) long life (> 100 kg Xe
throughput) magnetically shielded Hall thruster that features an internally mounted hollow …

We describe the effects of finite pressure in a large vacuum facility on a magnetically
shielded Hall thruster using internally and externally mounted cathodes. A numerical model …

The impact of facility conductivity on Hall effect thruster cathode coupling is experimentally
investigated. The 3.4 kW Aerojet Rocketdyne T-140 Hall effect thruster operating at a …

During the early development stages of Hall thruster technology, plasma research and
