SPECTRAL FLASH LAMP.
Abstract
Spectral data was obtained from gallium-thallium iodide flash lamps. The lamps were 0.5-inch inside diameter, six inches between electrodes, and xenon was used as a fill gas. Spectral radiance in the broadened lines of gallium and thallium was found to saturate approximately at the level of a 10,000 K black body. Input power higher than the minimum required for saturation of line radiance resulted in higher radiance from continum. Spectral data was obtained also from neon and xenon flash lamps of 0.5-inch diameter and 6 inches between electrodes. Spectral radiance in the red band equal to a 20,000 K black body was readily obtained with 150 microsecond flashes in neon lamps, and spectral radiance equal to a 30,000 K black body was readily obtained with 50 microsecond flashes.
