多像素光子计数器(Multi Pixel Photo Counter,简称 MPPC)是近几年发展起来的一种新型信号读出设备。为了对这种设备制作的闪烁探测器有较深入的了解和认知,本文配合塑料闪烁体,与 MPPC 制成塑料闪烁探测器,对利用这种新型的光子计数器做成的探测器进行了研究。利用它测试了塑料闪烁体的时间和位置分辨率,将这方面数据与之前常用的配有光电倍增管的闪烁探测器的数据进行了比较,能够了解到用 MP-PC 与塑料闪烁体做成的闪烁探测器在时间分辨和位置分辨方面能够达到实验的要求。在信价比和几何大小方面,MPPC 优于光电倍增管,因此利用 MPPC 将在实验方面带来很大的优越性,为实验研究提供更大的方便。

Muti-pixel photo counter (MPPC)is a new kind equipment of signal readout re-cently.In this paper,we make a plastic scintillator detector with the plastic scintillator and MPPC.In order to clearly know of the character of this scintillator detector,the performance of this kind of new plastic scintillator detector is tested.The time and position resolutions of the plastic scintillator are measured.The data are compared to that obtained by the previous plastic scintillator detectors which are connected with photo multiply tubes (PMT).Our ex-perimental results show that the time and position resolutions of plastic scintillator detector connected with MPPC can fit for the request of experiment.In terms of price ratio and the ge-ometry size,MPPC is better than PMT.As a result,making use of MPPC will provide much convenience for experiments.
