Development and Characterization of High-Efficiency, High-Specific Impulse Xenon Hall Thrusters
Development and Characterization of High-Efficiency, High-Specific Impulse Xenon Hall Thrusters by Richard Robert Hofer Chair: Associate Professor Alec D. Gallimore This dissertation presents research aimed at extending the efficient operation of 1600 s specific impulse Hall thruster technology to the 2000-3000 s range. While recent studies of commercially developed Hall thrusters demonstrated ...
متن کاملThe Role of Magnetic Field Topography in Improving the Performance of High-Voltage Hall Thrusters
Investigations of high-voltage Hall thrusters have indicated a peak in the efficiency versus voltage characteristic that limited the maximum efficiency to specific impulses of less than 3000 s. This peak is believed to be primarily a trait of modern magnetic field design, which is optimized for discharge voltages of 300 V. The NASA-173M has been operated at 300-1000 V and 5 mg/s to investigate ...
متن کاملEfficiency Analysis of a High-Specific Impulse Hall Thruster
Performance and plasma measurements of the high-specific impulse NASA-173Mv2 Hall thruster were analyzed using a phenomenological performance model that accounts for a partially-ionized plasma containing multiply-charged ions. Between discharge voltages of 300-900 V, the results showed that although the net decrease of efficiency due to multiplycharged ions was only 1.5-3.0%, the effects of mul...
متن کاملLarge Carbon-Carbon Grids for High Power, High Specific Impulse Ion Thrusters
NASA is investigating high power, high specific impulse propulsion technologies that could enable ambitious flights such as multi-body rendezvous missions, outer planet orbiters and interstellar precursor missions. Ion engines can efficiently operate at very high specific impulse, but accelerating voltages of many kV result in greater ion optics wear rates due to high energy ion bombardment. Th...
متن کاملDynamic Electromagnetic Field Measurements of Clustered Hall Thrusters
In an effort to verify the existence of and study the characteristics of the dynamic magnetic fields generated by supplying inner and outer coil Hall thruster electromagnets with wide bandwidth (DC to 200 kHz) currents, B-dot probe experiments have been performed. Several different locations were mapped and all three components of the magnetic field were recorded. A Helmholtz coil is used for h...
