| 摘 要： | 数字符合技术是目前国际放射性核素计量学研究的热点,是一种很有发展前景的、灵活的核脉冲处理技术.本文介绍了一种数字符合方法的实现方案,利用高速数据采集卡从探测器采集到的数据,并根据数字符合的特点,用Matlab软件对数字符合技术中的死时间、滤波、基线校正、脉宽分析和符合等算法进行研究.采用60Co源的β-γ符合测量活度实验进行验证,并得到了一些初步结果.

| Abstract: | Digital Coincidence Counting(DCC) is a promising,flexible nuclear pulse processing technology.In this paper,an implementation scheme of the digital coincidence is introduced.The nuclear detector signal was sampled to the computer by the high speed acquisition card,and then processed through Matlab.The relative Coincidence processing algoriths include deadtime processing,digital filter,baseline correction,pulse width analysis and digital coincidence algorith,and the preliminary results of β-γ coincidence measurement with 60Co source show that the realization scheme of DCC in this paper is practical. |
