Title: Development of an intelligent preamplifier for semiconductor detectors
Abstract: The results of engineering an intelligent preamplifier for high purity germanium gamma-detectors are presented. An intelligent preamplifier is a low-noise, high speed resistive feedback charge-sensitive preamplifier with a built-in microcontroller and additional units that enable control of preamplifier and detector parameters. It also allows the performance managing of the internal testing pulser, sensor of liquid nitrogen level in a Dewar, humidity, pressure and temperature sensors in a sealed preamplifier section. Intelligent preamplifier operation, set-up, and parameter measurements are controlled by a software.
