Results of a microscale line scanning (position steps of 10 µm) between the centres of two adjacent pixels (pixels No. 5 and No. 8) at energy above (40 keV) the K-shell absorption energy of CZT material. (a) Photopeak centroids and (b) multiplicity m for the 2 mm-thick detector were calculated. At 40 keV, even for beam positions near the centre of the pixels, the multiplicity is m ≥ 1, due to the presence of fluorescent X-rays. (a) The jump discontinuities present in the curves for peak centroid values around 4 keV are due to the non-zero energy threshold (3 keV).
