Abstract
Spectroscopic measurement using light-receiving optical fiber with relatively high spatial resolution was carried out to determine the excitation temperature near plasma jet fringe under strong magnetic field. Although the spatial resolution was improved by using a single fiber, measured emission intensity became weak due to narrow collection area. Some proper combinations of spectral lines were observed by the emission measurement for the present study. Therefore, it is possible to determine the excitation temperature by selecting an appropriate wavelength region that has spectral lines from the upper and lower excited levels around nearer region of the jet fringe.
