Умный предусилитель (SHP) для ОЧГ детекторов

Применение

State of Health Preamplifier (SHP) is a low noise and fast resistive-feedback preliminary amplifier intended for operation within gamma- and X-ray Detection Unit based on HPGe detector. SHP module allows to perform monitoring of detection unit basic parameters in real-time mode or per request of the operator. Specialized software SHP Center is used to display the parameters of the preamplifier in real time and control the settings. Analysis of the performance in the long run allows to predict possible failure of the detector and to perform timely preventive maintenance.
