A TES spectrometer operated at SPring-8 achieved 4 eV resolution at 6 keV, enabling XANES in fluorescence mode and clear separation of As K alpha from Pb L alpha2 lines plus detection of weak Fe signals in aerosols.
Figure 15 shows the XES of the two targets as the beam energy was swept across the Fe K-edge energy

Broad-band High-Energy Resolution Hard X-ray Spectroscopy using Transition Edge Sensors at SPring-8
A TES spectrometer operated at SPring-8 achieved 4 eV resolution at 6 keV, enabling XANES in fluorescence mode and clear separation of As K alpha from Pb L alpha2 lines plus detection of weak Fe signals in aerosols.
