The aim of this work is the study of the impact of the real preamplifier-detector configuration (i.e. finite bandwidth, input noise, leakage current, detector capacitance) on the measurement techniques used for fragment identification in charge and mass in multi-detector arrays for intermediate energy nuclear physics experiments. We refer to rise-time vs. energy diagram – that allows charge identification and ToF techniques – used for the identification of mass. In this work we derived a first model able to predict the detection system performance and useful to tailor both the detector and the front-end specifications to the specific experimental case. The requirements for the optimization result to be partly conflicting ToF technique requires fast timing signals, while pulse-shape analysis benefits from slower detector pulses.
