Laboratory X-Ray Imaging of High-Intensity Discharge Lamps

Abstract

We describe a laboratory-scale system for x-ray absorption imaging of the Hg vapor distribution in high-intensity discharge plasmas. This system utilizes commercially-available equipment, including an x-ray tube source. We analyze the sensitivity of the system and compare measurements made with this system to measurements made with synchrotron radiation (Curry, Sansonetti, and Wang, to be published in J. Phys. D: Appl. Phys. (2005)). The effect of the wide spectral distribution of x-ray tubes, as compared to the monochromatic spectrum of synchrotron radiation, is apparent in this comparison. In principle, it is possible to determine a correction factor, as a function of tube accelerating potential and photon path, to adequately compensate for this effect.
