摘要:

我们提出了一个数字信号处理系统的基础上,光子计数的方法,我们开发的热中子探测器组成的ZnS(Ag):6LiF掺杂层读出的WLS光纤和SiPM。已经评估了三种数字滤波器:移动和、微分后的移动和以及数字CR-RC^4滤波器。给出了采用这些滤波器的检测器的性能。采用CR-RC^4滤波器的全模拟信号处理已进行了数字仿真。用这种模拟方法获得的检测器性能与最佳性能的数字方法获得的一个比较。

英文摘要:

We present a digital signal processing system based on a photon counting approach which we developed for a thermal neutron detector consisting of ZnS(Ag):6LiF scintillating layers read out with WLS fibers and SiPMs. Three digital filters have been evaluated: a moving sum, a moving sum after differentiation and a digital CR-RC^4 filter. The performances of the detector with these filters are presented. A full analog signal processing using a CR-RC^4 filter has been emulated digitally. The detector performance obtained with this analog approach is compared with the one obtained with the best performing digital approach.
