抄録
An arcjet discharge device with a rectangular converging and diverging nozzle was developed, which allowed us to optically observe high-density plasma inside the anode nozzle Spectroscopic observation along the plasma expansion axis was carried out to examine the characteristics of the arc plasma inside the nozzle Analyzing intense continuum and line emission spectra, we successfully obtained spatial variations in electron temperature and density. Moreover, we found that two-dimensional optical measurement is highly useful in visualizing the transition from atmospheric thermal plasma to a strongly nonequilibrium recombining plasma due to adiabatic expansion.
