In the radiation detection system, amplifier is needed from very begging to the end. The first stage in the signal processing chain is the pre-amplifier. This pre-amplifier is usually located as close as possible to the detector to avoid noise pick-up in cables. In the next stage there is the main amplifier. Therefore, amplifier is the most important parts of the nuclear radiation detection system. In this research work a scintillation amplifier has been designed to meet the various requirements in radiation measurement. There are five basic units, which constitute the scintillation...
