3.1 Linking the various modules

The previous study showed that a signal whose maximum amplitude is proportional to the energy lost by the particle detected is obtained at the terminals of the load resistor R _c placed at the output of a detector. As the amplitude of this signal is always very low (of the order of just a few mV per MeV), it needs to be amplified while maintaining perfect linearity. In the chains used for simple nuclear radiation spectroscopy, the various operations are performed by a series of specific modules linked together by connecting cables. For obvious commercial reasons, and for the user's peace of mind, most of these modules follow NIM (Nuclear Instrument Module) standards, ensuring perfect compatibility between...
