Abstract

The aim of this work was to characterize two large-area, highly-segmented, 1.5-mm thick silicondetector prototypes, with the goal of using them during in-beam experiments, in order to investigatenuclear structure properties by particle and gamma-ray spectroscopy.Such characterization consisted, after having identified the depletion voltage by different approaches,in the estimate of the best energy and time resolution. In the case of the energy resolution, optimalfilter parameters have been determined by a scan and by applying the FFT transform to identify themain noise contributions. Timing properties have been scrutinized using a digital constant-fractionalgorithm to efficiently restrain time jitter and walk. Eventually an estimate of charge-sharing effectsand resistivity of the substrate have been achieved
