Journal ArticleDOI
Plasma Properties in the Plume of a Hall Thruster Cluster
TL;DR: In this paper, the plume density, electron temperature, and plasma potential data collected with a combination of triple langmuir probes and floating emissive probes in a low-power, four-engine Hall thruster cluster are presented.
ReportDOI
Preliminary Plume Characterization of a Low-Power Hall Thruster Cluster
TL;DR: In this article, the authors used a triple Langmuir probe to measure the plasma density, electron temperature, and plasma potential in the Busek BHT-200-X3 Hall effect thrusters and found anomalously high electron temperatures along the centerline of each thruster.
Proceedings ArticleDOI
Laser induced fluorescence measurement of ion velocities in the plume of a hall effect thruster
Journal ArticleDOI
Plasma properties downstream of a low-power Hall thruster
TL;DR: In this article, the authors measured the electron number density, electron temperature, and plasma potential downstream of a low-power Hall thruster using three Langmuir probes and emissive probes.
Journal ArticleDOI
Effects of cathode configuration on hall thruster cluster plume properties
TL;DR: In this paper, the plume properties and discharge current characteristics obtained with multiple Hall thrusters coupled to a single cathode were analyzed and compared to those obtained with each thruster coupled to its own independent cathode.
