Parallelization of particle-in-cell simulation modeling Hall-effect thrusters
MIT's fully kinetic particle-in-cell Hall thruster simulation is adapted for use on parallel clusters of computers. Significant computational savings are thus realized with a predicted linear speed up efficiency for certain large-scale simulations. The MIT PIC code is further enhanced and updated …

Two dimensional particle-in-cell simulation model for Hall type thrusters
In this master's thesis, a two-dimensional model of a Hall type thruster, was developed, to include secondary electron emission at the wall, ion recombination at the wall, diffuse reflection for neutrals bouncing off of the wall, wall potential calculation based on the collected wall charge and a …

Numerical models of Hall thruster ionization oscillations
In this thesis, low frequency ionization oscillations in Hall thrusters resembling the breathing mode are studied through computational simulation. The relationship between wall erosion and discharge current oscillations is analyzed using particle-in-cell simulation, and a series of parametric …

Performance testing and internal probe measurements of a high specific impulse Hall thruster
… Hall thruster was used for performance testing and internal plasma measurements to support the ongoing development of computational models. The thruster was performance tested in both single and two stage anode configurations. In the single stage configuration, the specific impulse exceeded …

Computational and theoretical study of electron phase-space holes in kinetic plasma: kinematics, stability and ion coupling
In this thesis, a comprehensive study of Bernstein-Greene-Kruskal (BGK) mode electron holes in a collisionless plasma where strong kinetic effects are important is presented. Kinematic theory based on momentum conservation is derived treating the electron hole as a composite object to study the …
