HIGH-POWER electric propulsion (EP) systems with input power levels greater than 10 kW
are now being considered and implemented on various space missions. This is primarily …

We demonstrate a technique by which erosion of the acceleration channel in Hall thrusters
can be reduced by at least a few orders of magnitude. The first principles of the technique …

The research challenges for electric propulsion technologies are examined in the context of
s-curve development cycles. It is shown that the need for research is driven both by the …

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

A Hall thruster is a cross-field plasma device used for spacecraft propulsion. An important
unresolved issue in the development of Hall thrusters concerns the effect of discharge …

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 …

The successful application of a fully shielding magnetic field topology in a low-power Hall
thruster is demonstrated through the testing of the MaSMi-60 Hall thruster (an improved …

Since the inception of the Hall-effect thruster more than five decades ago, many theories
have been proposed about the source (s) of the anomalous cross-field transport that is …

The performance of a 9-kW class magnetically shielded Hall thruster operating on xenon
and krypton propellants is experimentally characterized. Thrust and efficiency …

Mode transitions in a 6 kW laboratory Hall-effect thruster were induced by varying the
magnetic field intensity while holding all other operating parameters constant. Ultrafast …
