註釋An experimental facility has been built to utilize the advantages of cooled optical surfaces in infrared measurements. With liquid nitrogen cryogen, significant enhancement of signal-to-noise ratios in the 1-to 10-micron region and some enhancement at longer wavelengths are obtained. The facility is coupled to an electron-beam generator as the excitation source. At present, data have been obtained in the short-wave infrared radiation (SWIR) in air, nitrogen, and oxygen at pressures in the subtorr region. Oxygen has shown only atomic line radiation in the 1.6- to 5.6- micron band. Nitrogen shows substantial radiation in the same wavelength region with frequently overlapping band systems extending to at least 4 micron, due to several different electronic states. Air shows many of the same systems with NO at 2.7 and 5.4 micron as the most intense features. (Author).
