Demountable X-Ray Tube for Light Element Fluorescence Analysis
A primary X-ray source suitable for the fluorescence analysis of elements ranging from chlorine to boron (Z=17—5, respectively) is described. The tube, based on the concept of Prof. B. L. Henke, Pomona College, Claremont, California, has been designed to allow utilization in the general X-ray laboratory. Targets can be changed and filament replaced. A vacuum isolation gate is provided to permit the convenient utilization of extremely thin windows, which can be changed without disturbing tube vacuum. Separate water-cooling systems are provided for the anode itself and the outer shell. Detailed data on tube operating parameters are given, and the X-ray generator designed to power this tube is described.
