摘要
本文设计了一种基于ZYNQ的γ能谱测量系统,用于瞬发中子活化分析仪中NaI探测器的γ能谱测量。γ能谱采集系统主要包括高压电源、数字多道幅度分析系统以及上位机等,可实现高达130 Msps的采集频率以及千兆以太网的数据传输及控制。经^(137)Cs、^(60)Co、^(152)Eu等放射源的测试,γ能谱采集系统能谱响应线性拟合优度为0.999,能量分辨率为8.76%(@0.662 keV)。结果表明,该γ能谱采集系统性能达到煤质成分检测的能谱测量要求。
This article presents aγ-ray spectrum measurement system based on ZYNQ,designed forγ-ray spectrum measurement of NaI detectors in transient neutron activation analyzers.Theγ-ray spectrum acquisition system mainly includes a high-voltage power supply,a digital multi-channel amplitude analysis system,and an upper computer,capable of achieving a sampling frequency of up to 130Msps and data transmission and control via Gigabit Ethernet.Through tests with ^(137)Cs,^(60)Co,and ^(152)Eu radioactive sources,theγ-ray spectrum acquisition system exhibits a linear fitting goodness of 0.999,with an energy resolution of 8.76%(@0.662 keV).The results demonstrate that the performance of thisγ-ray spectrum acquisition system meets the spectrum measurement requirements for coal quality component detection.
