在过去的二十年中,微模式气体探测器被广泛应用于粒子探测的位置测量。本文提出了一种新的快中子径迹识别和重建方法。该方法由于信号持续时间较短,可消除γ本底。根据模拟数据分析,在入射中子通量为109 s-1,γ中子比为9:1的情况下,该方法对快中子的探测效率为0.4%,位置分辨率为0.3mm。为了验证该方法,还进行了241 Am的测量,并详细介绍了测量中使用的数据采集系统。基于该方法,可以在基于FPGA的数据采集系统中构建在线跟踪系统,从而显著提高计数率和空间分辨率的能力。
Micro pattern gaseous detectors have been widely used in position measurements of particle detection in the last two decades. In this work a novel method of track identification and reconstruction was developed for fast neutron detection. In this method the γ background could be eliminated as their signal duration is shorter. According to the analysis based on simulation data, with an incident neutron flux of 1 0 9 s− 1 and a 9-to-1 γ-neutron ratio, this method achieved a detection efficiency of 0.4% for fast neutron, with a position resolution of 0.3 mm. To demonstrate this method, a measurement of 241 Am was also done and the detail of the data acquisition system used in the measurement was presented. Based on this method, an on-line tracking system can be built in an FPGA-based data acquisition system to significantly improve both the capability of counting rate and the spatial resolution.
