Abstract :
We present our results from testing 15×15×10 mm3 CdZnTe pixelated detectors using a readout system based on the H3D ASIC. Data obtained with an uncollimated 137Cs source helped reveal details of the operational principle of such devices, and how the pulse-processing electronics may influence their performance. The responses of individual pixels were compared by using two different pulse processing approaches based on the analog shaping (H3D ASIC) and fitting of the waveforms as read out from hybrid preamplifiers.
