Stainless Steel Analysis Using Compact 3D-polarized XRF Spectrometer

Abstract

We assemble a compact three dimensional-polarized X-ray fluorescence (XRF) spectrometer with a low wattage power X-ray tube (four watts, tungsten target) and measure stainless steels. We use acrylic resin as a polarizer and the incident X-rays are polarized by the Compton scattering. We find that the intensity of nickel Kα of the 3D-XRF spectra is less than that of 2D-XRF spectra because of the shift of tungsten Lα line to the lower energy side of the nickel absorption K-edge by the Compton scattering.
