The energy spectra after CSA with the collimated synchrotron X-ray beams positioned at the centre of the inter-pixel gap between pixels 5 and 8 of (a) the 500 µm and (b) 250 µm arrays of the 2 mm-thick REDLEN detector. The photopeaks are both widened and shifted to lower energies (energy shifts > 10%), confirming the presence of charge losses at the inter-pixel gap. |
