摘要：

A description is given of the design and performance of a novel fluorescent x-ray source, comprising a demountable conical target enclosed in a conical anode x-ray tube. Measurements are presented of the spectral purity of the fluorescent emission and the variation in photon flux with the applied tube voltage. A Ta target tube (K(alpha-1) = 57.532 keV) powered by a standard 3.75 kW, 160 kV high voltage generator has a source brightness of 10(9) photons/s sr mm2. ThiS is 500 times greater than that of the brightest available Am-241 radionuclide sources. Some potential applications of the fluorescent x-ray source are listed.
