Relationship Between X-Ray Tube Target Materials and X-Ray Emission Intensities
Factors affecting fluorescent intensity from a sample in an X-ray spectrograph are reviewed. Excitation efficiencies of monoenergetic X-ray sources are discussed and data on low atomic number elements are given. For polychromatic X-ray spectra, effective wavelengths and excitation efficiencies are measured as a function of atomic number. A new dual-target X-ray tube is shown to be an effective answer to the problem of covering a broad range of elements with a single X-ray tube.
