説明

Effects of the outer gas flow rate on spectral intensities and SBRs were investigated for various excitation energies of spectral lines and observation heights. The influences of the outer gas flow rate on spectral intensities were unexpectedly great and markedly varies with excitation energies and observation heights. The influence at a lower observation height (e.g. 10 mm) above the load coil was especially severe and complicated.<BR>Effects of the outer gas flow rate on the background continuum intensity were also investigated. The background intensity increased with an increase in the outer gas flow rate at an longer wavelength (e.g. 400 nm) but decreased at an shorter wavelength (e.g. 220 nm). This phenomenon can be explained based upon both temperature dependence of the emissivity of radiative recombination as a function of wavelength and influence of the outer gas flow rate on the optical thickness for background emission.
