INFRARED SPECTRA AND TEMPERATURES OF PLASMAJETS: SPECTROMETRIC AND SPECTRORADIOMETRIC MEASUREMENTS OF PLASMAJET TEMPERATURE DISTRIBUTIONS

Abstract

Temperatures of plasmajets were measured by several optical methods and the results intercompared. Both spectrometric and spectroradiometric methods were used. Argon and nitrogen plasma jet temperatures were studied in particular detail. Large temperature gradients were observed in all plasmajets studied. Spectra of plasmas were measured in both emission and absorption over the spectral range 0.37 to 5.0 microns. Substantial emission was observed throughout the entire region. All the plasmas proved to be optically thick (measurable absorption) in the region of 0.7 - 2.0 microns and optically thin (no absorption) in the region 0.37 - 0.7 microns.
