The Detected Method of Gamma Peak Based on FPGA

在石油测井行业中伽玛能谱的测量是一种很重要的测井方式,本文结合脉冲中子能谱测量,对伽玛脉冲峰值检测做了研究,利用微分、延时电路及FPGA器件,能很好地检测到伽玛信号的峰值,由实验结果可知,峰值检测的线性度基本满足能谱测量的需求。

The measure of Gamma spectrometry is a very important method of logging in its field. In this paper, the research is done to pulse peak detector gamma combined with pulsed neutron spectrum measurement. Using the differential, it can well detect the peak of gamma signal with the delay circuit and FPGA devices. The peak detector linearity can meet the needs of Spectrometry accord- ing to the experimental results.
