Unformatted text preview: to (1) backscattering of electrons and the associated production of additional x-ray signal; (2) backscattering electrons decrease the number of electrons at depth that are able to produce x-rays, (3) with increasing depth, the energy of the electrons is reduced due to multiple inelastic collisions, and are no longer energetic enough to produce characteristic x-ray producing transitions. CBEMS 164 – XRD, SEM & Microanalysis: Lecture 13 ! 36 X-ray Generation with Depth, (z):! •  Process the spectra of the specimen and standards to remove the background, which results from the x-ray continuum, from the x-ray peaks, so that the measured intensities consist only of...
