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 …

This paper provides perspectives on recent progress in understanding the physics of
devices in which the external magnetic field is applied perpendicular to the discharge …

Hollow cathode plasma discharges are a fundamental part of a large variety of applications
in industry, academia, and space. From surface processing and coatings deposition to …

A two-dimensional axisymmetric quasi-neutral fluid model of an emissive hollow cathode
that includes neutral xenon, single charge ions and electrons has been developed. The gas …

Magnetic shielding of Hall thrusters has been shown to reduce erosion of the channel walls
by at least a few orders of magnitude, thereby enabling the use of these devices in deep …

A numerical emissive hollow cathode model which couples plasma and thermal aspects of
the NASA NSTAR cathode has been presented in a companion paper and simulation results …

The presence of instabilities in a low density, low temperature plasma expanding through an
axially symmetric magnetic nozzle is investigated in the context of non-classical electron …

A frequency-averaged quasilinear model is derived and experimentally validated for the
evolution of ion acoustic turbulence (IAT) along the centerline of a 100-A class, LaB 6 hollow …
