1. In an SEM, we are usually limited to 25-30 keV beam energies. Because we you can't geta signal that is higher energy than your probe (conservation of energy), this also serves to limit the spectral range across which we can perform XEDS measurements. As such, XEDS spectra are typically recorded across the range of 0-20 keV (usually avoiding getting too close to the beam energy itself in order to avoid large Bremsstrahlung signals). With this in mind, assume you are performing XEDS measurements on a specimen containing Mg, Zn, Ag, and Au. (a) [1.5pts] What are all the possible K, L, and M characteristic X-ray lines that you would expect to easily detect? Assume your equipment can only detect the strongest peak in each of the line families (i.e. K, L, M) for each element. (b) /1.5pts] Using your favorite spreadsheet program, plot all of the expected peaks on a bar graph (don't try to provide realistic resolution, just assume the peaks are true lines). Estimate the relative intensities of the different lines using the fluorescence yield relationship (Note: a; ~ 1.0x10 for K, ~7.2x107 for L, and ~1.2x10 for M)
