Figure 7
Fluorescence signals normalized to I0 as measured from a 55 µmole Cu solution using a four-element SDD detector and the plastic collimator. The top plot shows the total signal on the detectors summed over all energies, while the bottom is for the Cu ROI (7800–8280 eV). In the top panel the filter curve has been shifted upwards by 14 units vertically for comparison. |
