摘要

To directly observe an arcjet inside the plasma discharge section, we developed an arcjet plasma device having a converging and diverging slit nozzle. Spectroscopic observations in the directions parallel and perpendicular to the plasma expansion axis were made to examine the characteristics of the arcjet plasma inside the nozzle. Intense continuum spectra due to bremsstrahlung were observed at visible and infrared wavelengths, from which the two-dimensional spatial distribution of the electron temperature was obtained. In addition, the electron density was determined by using the Stark broadening spectrum; the result indicated that high-density plasma was generated in the nozzle.
