Evaluation and Active Control of Clustered Hall Thruster Discharge Oscillations
While preliminary experiments with a cluster of four Busek 200-Watt (BHT-200-X3) Closed Drift Hall thrusters indicate reasonable performance scalability from single thruster experiments, cluster plume interactions are believed to give rise to an increased ion energy spectrum as well as cross-talk and synchronization between the thruster discharges. Recent experiments with a higher power cluster...
متن کاملMultiscale Modeling of a CAMILA Hall Thruster Discharge
Copyright c ©2017 by the Aerospace Plasma Laboratory, Technion. Published by the Electric Rocket Propulsion Society with permission. A multiscale model was developed for the channel of a CoAxial Magnetically Insulated Long Anode (CAMILA) Hall effect thruster. The computational domain was subdivided into a region where a hybrid solver is used and a region where a fully kinetic particle in cell s...
متن کاملTime-evolution of the ion velocity distribution function in the discharge of a Hall effect thruster
The temporal characteristics of the Xe ion axial Velocity Distribution Function (VDF) were recorded in the course of low-frequency discharge current oscillations (∼ 14kHz) of the 5 kW-class PPSrX000 Hall thruster. The evolution in time of the ion axial velocity component is monitored by means of a laser induced fluorescence diagnostic tool with a time resolution of 100ns. As the number of fluor...
متن کاملPlasma Potential Measurements in the Discharge Channel of a 6-kW Hall Thruster
In an effort to understand the role of neutral flow dynamics in the operation of Hall thrusters, a floating emissive probe was used to measure the plasma potential, electric field, and electron temperature in the discharge channel of a 6-kW Hall thruster operating at 300 V and anode flow rates of 10, 20, and 30 mg/s. To isolate the effect of propellant flow rate, the cathode flow fraction and m...
