Figure 4
The energy resolution (FWHM) and the peak-to-background ratio (P/B) for the Ni K-fluorescence line (E = 7.47 keV) as a function of the total incoming count rate (TCR), measured for a seven-pixel SDD. A sample consisting of 1.8 wt% Ni/7.1 wt% Mo/Al2O3 served as a fluorescing object (irradiation with 12 keV photons). |
