Complementary Density Measurements for the 200W Busek Hall Thruster (PREPRINT)

Abstract

Results of two complementary methods of measuring the near field plasma densities of a 200W Busek X3 Hall thruster are presented. Both a Faraday probe and microwave interferometry system are used to examine the density distribution of the thruster plasma at regular spatial intervals. Both experiments are performed in situ under the same conditions. The resulting density distributions obtained from both experiments are presented. Advantages and uncertainties of both methods are presented, as well as how comparison between the two data sets can account for the uncertainties of each method alone.
