Abstract: A high-temperature pulse light source has been developed for use in high-speed photography, high-temperature pyrometry, plasma spectroscopy, etc. Like a standard source it dependably maintains a constant radiation brightness notwithstanding the amount of use and storage time. The radiant source is provided by an electrical discharge with rectangular-shaped light-pulse pattern in a capillary with both ends open. The capillary is made of a shatter-proof plastic. The source radiates a uniform continuous spectrum in the 1900 to 7000 A range, with line emission and absorption contributing not more than 1%. The absorption ability of the discharge plasma in the visible and ultraviolet is close to unity because of the high pressure (∼500 atm) created in the capillary simultaneously with the discharge process. Photoelectric measurements show that, in the 2500 to 6000 A range, the radiation of the pulse source corresponds to that of an absolutely black body at 39,000 ± 2000 K.
