Sheet Velocity Measurements Using Laser Absorption Spectroscopy in a Xenon Hall Effect Thruster Plume

Abstract

A new laser absorption spectroscopy (LAS) velocimetry system, designed to obtain2D planar velocity fields for ionized Xenon in the plume of a Hall effect thruster by probing the transition of Xe II at 834.72 nm, was implemented at the Air Force Institute of Technology (AFIT) Space Propulsion Analysis and System Simulator(SPASS) Lab vacuum chamber. A single horizontal laser sheet was used to probe singly-ionized Xenon in the plume of a Busek BHT-600 Hall thruster and obtain a histogram of estimated axial velocity, to validate the system. Similar velocities to those obtained by an earlier intrusive characterization of the thruster were observed.
