Figure 5
(a) Spatial (gray scale) and statistic (blue) distribution of the energy resolution as the FWHM of the Mn Kα peak obtained with a ⁵⁵Fe source for the DESY Maia 384C7 detector. An average energy resolution of 255 eV FWHM with 71% of the 384 detector elements showing an energy resolution better than 260 eV was determined. (b) The average energy resolution of the detector shown as a function of count rate at two different preamplifier shaping times, 2 and 4 µs. These data were obtained from irradiating a thin Fe target with synchrotron radiation of 11 keV.
