Comparison of Fe K-edge XAFS spectra collected with the CVD diamond micro-detector and the routine IC. (a) The experimental k2χ(k) oscillations. (b) The Fourier transform (FT) spectra of k2χ(k). (c) The isolated near-neighbor oscillations and their best-fit curves. (d) The FT spectra of oscillations and their best-fit curves. In panels (c) and (d), the data of the CVD diamond micro-detector (upper) have been shifted up relative to the data of the routine IC (lower) for clarity.
