摘要
为了研究数字化γ能谱仪,采用现场可编程逻辑部件(FPGA),完成数字多道脉冲幅度分析仪的硬件设计。用QuartusⅡ软件在FPGA平台上完成了数字核脉冲的幅度提取并生成能谱。在此基础上通过电路设计建立了数字化能谱测量实验装置,实测了137Cs的能谱,测量结果与相同条件下的模拟能谱仪的实测谱完全吻合。由此证明基于FPGA的数字多道脉冲幅度分析器硬件设计正确可行,具有实用性。
In order to develop a digital gamma spectrometer,an FPGA based digital multi-channel pulse height analyzer was designed with hardware description language.Software QuartusⅡ was used on FPGA platform to complete the digital nuclear pulse amplitude extraction and generate energy spectrum.On this basis,the real circuits were designed and an experiment device of the digital energy spectrometry was built.The gamma energy spectrum of137Cs was measured with the spectrometry device.The measured result coincides well with that from the spectrometer in the same measuring conditions.It is proved that the hardware design of the digital multi-channel pulse height analyzer based on FPGA is correct and has practical applicability.
