DENSITY MEASUREMENTS OF NEUTRAL XENON USING MULTIPHOTON IONIZATION AND MICROWAVE SPECTROSCOPY IN A HALL EFFECT THRUSTER

Abstract

A new dye laser and microwave scattering system for measuring low speed xenon particles was installed to characterize a commercially sourced 600 W Hall effect thruster. The new system uses multiphoton ionization and microwave spectroscopy to determine number density and velocity measurements of neutral xenon atoms in the plume of a Hall thruster. A study was conducted to ensure the new system will be able to accurately measure these neutrals in future work. The ultimate goal of this new system is to isolate and characterize the extra thrust produced in Hall Effect Thrusters due to finite volume vacuum chambers.
