In order to meet the demand of lightning high energy radiation data acquisition, a high energy gamma ray data acquisition system is designed. According to the structure and processing capacity of high-speed sampling electronics system, the analog signal conditioning, high-speed ADC and data analysis and control circuit design, using the current sensitive signals filtering before forming, dual channel ADC acquisition, spectral and time resolution of spectrum data technology, realize the instantaneous high-energy gamma radiation in real-time, accurate and reliable screening events. The results show that the system reflects the actual demand and has certain reference value.
