Plot of the energy resolution vs. incoming γ-ray energy, for a system composed of a scintillator crystal coupled to a photodetector. It is possible to distinguish three regions, each one dominated by a particular contribution to the resolution. In the region on the right side of the graph, above few hundreds of keV, scintillator non idealities dominates with respect to the other contributions. Fig. 2. Layout of the Silicon Drift Detector used for the γ-ray measurement. On the left side of the figure one can see the bonding pads, which are external to the active area and are connected to the central region of the device.
