High Definition X-Ray Fluorescence: Principles and Techniques

WebTraditional wavelength dispersive X-ray fluorescence (WD) spectrometers comprise a high power X-ray tube (typically 3-4 kW power dissipation), a sample presentation device and an X-ray monochromator to measure the fluorescence spectrum. Rapid advances in semiconductor technology in the 1970’s WebCharacteristic X-ray. Characteristic X-rays are emitted when outer- shell electrons fill a vacancy in the inner shell of an atom, releasing X-rays in a pattern that is "characteristic" to each element. Characteristic X-rays were discovered by Charles Glover Barkla in 1909, [1] who later won the Nobel Prize in Physics for his discovery in 1917.
