Design of Gamma Spectrometer Based on NI software and Hardware Platform

The gamma spectrometer is a radiometer that measures the gamma ray energy distribution and radiation dose. It is an important nuclear science physics method. It is one of the main methods to solve the problems of the earth sciences, environmental sciences and other issues. In this paper, virtual instrument technology is applied to the design of gamma spectrometer. The whole system consists of detectors, signal conditioning circuits, high-speed A/D acquisition cards, and upper-level performance analysis and processing software. It will detect gamma-ray conversion. As the trigger pulse, the pulse signal and the trigger signal are transmitted to the acquisition card at the same time, and the collected pulse data is transmitted to the computer for processing. The computer receives the data transmitted by the high-speed acquisition card to realize the detection, acquisition and analysis of the spectrum signal. The research, processing, storage, display, printing, retrieval and network transmission functions have important theoretical and practical values.
