ENERGETIC AND RADIATIVE CHARACTERISTICS oF A PULSE SHORT-ARC XENON LAMP IN THE REGIMES OF “SATURATED” LIGHT BRIGHTNESS
Abstract
The results of investigating electrical, power and spectral radiation properties of an experimental three-electrode xenon flash lamp are presented. The lamp was operated at high-pressure in the regimes close to the maximum spectral brightness limit of xenon emission. It was shown that in the regime of saturated brightness (the black-body temperature in the visible spectral range ~30000 К) the radiation of the pulsed discharge in xenon differs significantly from the radiation of an absolutely black body: the maximum black-body temperatures were 24000 and 19000 K for UV and near IR ranges, respectively. The relative portion of UV radiation in the lamp emission spectrum is more than 50%, which allows to consider such lamps as promising broadband radiation sources of high spectral brightness for many actual practical applications.
