Abstract:
The spectral distribution of the continuum radiation of nitrogen and argon plasma was measured for temperatures ranging from 8000K to 13000K at atmospheric pressure. The wavelength interval, 2680 A to 20900 A, over which the nitrogen continuum was investigated accounts for approximately 90 percent of the total energy radiated by the continuum. The spectral distribution of the continuum is integrated to obtain a measurement of the total continuum energy radiated from nitrogen. These data are compared with direct measurements of the total radiation and with a number of theoretical predictions. These comparisons indicate that atomic line radiation is not an important contributor to the total radiation for the conditions under investigation and that another source of continuum radiation such as the negative nitrogen ion may be an important contributor in the visible region of the spectrum. Electrical and thermal conductivities of nitrogen and argon plasma were measured over the temperature range from 8000K to 13000K at atmospheric pressure. Comparison is made between theory and other experimental investigations. Author
