The current status and challenges of the discharge plasma modeling capabilities in Hall
effect thrusters (HETs) are reviewed. Partially magnetized plasmas in HETs present unique …

There are a number of pressing problems mankind is facing today that could, at least in part,
be resolved by space systems. These include capabilities for fast and far-reaching …

The performance of a three-channel, 100-kW nested Hall thruster was evaluated on xenon
propellant for total powers up to 102 kW. The thruster demonstrated stable operation in all …

Expected high electron mobility and low resistivity along magnetic field lines—as compared
to across magnetic field lines—have led to the assumption, or the reproduction through a …

Magnetically shielded Hall effect thrusters suffer from pole erosion as their life-limiting
mechanism. However, the dominant physical mechanism causing this erosion remains …

Electric propulsion has become the favored approach for Low Earth Orbit (LEO) maneuvers,
resulting in substantial expansion in its use in the satellite industry. The Hall effect thruster's …

A direct kinetic (DK) simulation is capable of modeling the nonequilibrium state of plasma as
it evolves in the discharge region of a Hall thruster without the numerical noise that is …

The development of new space missions and the growing interest in space exploration have
created an urgent need to develop high-thrust propulsion systems capable of propelling …

We developed a new experimental approach to characterize the plasma behavior inside
Hall thrusters. The main novelty of the developed approach regards the combination of a …

This article reports on the characterization of a laboratory model 100 A-class hollow cathode
with a sintered lanthanum hexaboride (⁠ LaB 6⁠) emitter for high-power Hall thrusters. The …
