High-resolution X-ray spectrometry of solids using the microcalorimeter X-ray detector

摘要

We analyze here the spectrum of the Al Kα and Mg Kα X-ray lines obtained by electron excitation of a multielement glass. The spectrum was obtained in an electron beam probe using a microcalorimeter X-ray detector. With 7 eV resolution, we are able to observe and compare the intensity ratios of the Kα_(3, 4) satellites to the Kα_(1, 2) main lines. These satellites are sensitive to the chemistry of the solid. We compare our observed values to the intensity ratios obtained by Klauber and by Krause & Ferreira. The agreement of the relative satellite intensities in our measurement is more consistent with ratios for metals than for oxides. The ability to observe satellites of lines in multielement samples using the microcalorimeter detector opens up new possibilities for the interpretation of atomic core-valence processes in solids.
