Plume characteristics of a magnetic layer type Hall thruster were evaluated by laser absorption spectroscopy and single probe measurement. Translational temperature and total number density distributions of xenon atom were deduced using an absorption line of XeI 823.16 nm and electron temperature. As a result, the temperature was around 430±50 K in the almost all measured region, which agreed with the thermocouple measurement though it might be overestimated 850 K at the channel exit due to the Zeeman effect. The maximum total number density was 3.9x10 19 m-3 at the channel exit. Then, the number density decreased by one order at 200 mm away from the exit.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
