Figure 6
Illustration of the ATHENA XAFS dead-time correction. Shown is the SDD spectrum from SrMnO3 uncorrected for dead-time, the SDD spectrum corrected for dead-time assuming [\tau_{\rm{d}}^{\,\rm{ICR}}] = 0 (simple correction), and the SDD spectrum corrected for dead-time using the experimentally determined values for [\tau_{\rm{d}}^{\,\rm{ICR}}] (full correction). The SDD spectra are compared with the spectrum acquired by an ion chamber that suffers no dead-time loss. Note that in the latter case the two spectra are indistinguishable. The inset shows an expanded view of the Mn pre-edge feature.
