Popis: The usual requirement for a spectrometer system is to provide the best energy resolution that can be obtained with a set of given experimental constraints. These constraints can change with each experiment, and the experimenter should be able to optimize the parameters of the spectrometer to obtain the best results. The detector, either silicon or germanium, is connected to a charge-sensitive preamplifier. The detector produces short current pulses of a width equal to the collection time of the detector. These are integrated by the charge-sensitive preamplifier which produces a voltage step at its output. The output step rise time is equal to the collection time of the detector, its amplitude is equal to the input charge divided by the capacitance of the feedback capacitor, and its decay time constant is determined by the preamplifier feedback components.
