Near-field angular distributions of high velocity ions for low-power hall thrusters [PDF]

open access: yes, 2009
Experimental angular distributions of high-energy primary ions in the near-field region of a small Hall thruster between 50-200 mm downstream of the thruster exit plane at a range of centerline angles have been determined using a highly-collimated ...

2D Fluid-PIC Simulations of Hall Thrusters with Self-Consistent Resolution of the Space-Charge Regions

open access: yesPlasma, 2023
Many hybrid simulations of Hall thrusters, where electrons and ions are solved using hydrodynamics and particle-in-cell methods, respectively, assume that the ionized gas is quasi-neutral everywhere in the computational domain and apply so-called thin ...

Study on the influence of discharge voltage on the performance of Hall propulsion system

open access: yesAIP Advances, 2023
The discharge characteristics of the Hall thruster are numerically studied at different discharge voltages when the magnetic field does not change based on the particle in cell plus Monte Carlo collision methods.

Optimization of a Faraday Cup Collimator for Electric Propulsion Device Beam Study: Case of a Hall Thruster

open access: yesApplied Sciences, 2021
A Faraday cup (FC) is an instrument dedicated to current measurement in beams, jets and plasmas. It consists of a set of polarized electrodes mounted in such a way plasma sheath effect can be neglected, yielding accurate and reliable results.

Computation of Neutral Gas Flow From a Hall Thruster Into a Vacuum Chamber [PDF]

open access: yes, 2003
The finite pressure present in vacuum chamber testing of space propulsion systems such as Hall thrusters can have a number of undesirable effects. For example, the thrust generated by the thruster is higher and the plume divergence angle larger in ground

A review of Hall thruster plume modeling [PDF]

open access: yes38th Aerospace Sciences Meeting and Exhibit, 2000
Hall thrusters are an attractive form of electric propulsion that are being developed to replace chemical systems for many orbit propulsion tasks on communications satellites. A concern in the use of these devices is the possible damage their plumes may cause to the host spacecraft.
