Figure 7
Measured energy spectra to mono-energetic synchrotron X rays collimated (ϕ = 10 µm × 10 µm) at the centre of the central pixel of (a) large and (b) small arrays. Energy spectra at 25 keV and at 40 keV are presented. The energy resolution values (FWHM) are 1.8 keV and 2.0 keV for the large and small arrays, respectively. |
