Transport Physics in Hall Plasma Thrusters
An analysis of measurements supporting the presence of anomalous cross-field electron mobility in Hall plasma accelerators is presented. Non-intrusive laser-induced fluorescence measurements of neutral and ionized xenon velocities, and various electrostatic probe diagnostic measurements are used to locally determine the effective electron Hall parameter inside the accelerator channel. These val...

متن کاملExperimental Investigation of High Frequency Plasma Oscillations Within Hall Thrusters
[Abstract] An experimental setup has been developed to measure high frequency plasma oscillations within the acceleration channel of a laboratory Hall thruster. The plasma oscillations are measured with three Langmuir probes separated by small axial and azimuthal offsets. This configuration permits the oscillations to be correlated with direction and wave number. This work is motivated by the a...
متن کاملPlume Model of Hall Effect Plasma Thrusters with Temporal Consideration
Introduction Experiments were conducted to develop a As the development of Hall effect plasma thrusters comprehensive plume model for Hall effect plasma continues, potential missions beyond basic north-south thrusters. The purpose of the plume model developed in and east-west station keeping are being considered for this this paper is to give system integrators a guide to follow type of thruste...
متن کاملMultiscale Modeling of Hall Thrusters
Multiscale Modeling of Hall Thrusters Hall thrusters are efficient space propulsion devices that produce thrust by accelerating quasineutral plasma. The thruster consists of a channel with one end open to the ambient environment. The neutral propellant is injected at the closed end and is ionized by electrons produced by an externally mounted cathode. A radial magnetic field is applied across t...
