X‐ray fluorescence analysis using intensive linear polarized monochromatic x‐rays after bragg reflection

P. Wobrauschek, H. Aiginger

Abstract

Abstract To obtain intense linear polarized monochromatic X‐rays a single crystal where Bragg reflection occurs at an angle 2θ=90° is used. A number of suitable crystal materials is listed which fulfil the requirements of the Bragg equation for the wavelengths of standard X‐ray tubes and the angular condition. As the first result of a new construction a detection limit of 1 ng Ca was determined using a Cr anode and a Ta single crystal (002) plane as polarizer.
