论文摘要
在本文中，我们介绍了江门地下中微子天文台（JUNO）实验的大型照相型管（PMT）后灌肠测量结果。测试了来自Hamamatsu公司的11个Dynode-PMT（R12860）和150个微通道板PMTS（MCP-PMTS，GDB-6201）的NNVT Company的150个Dynode-PMTS（MCP-PMTS，GDB-6201）。对于经过测试的MCP-PMTS（Dynode-PMTS）的总脉冲电荷与主脉冲电荷之间的延迟为0.5 $ $ s和20 $μ$ S之间的平均比率为5.6％（13.2％）。 Juno实验将部署20,012 20英寸PMT，这项研究将使Juno实验的检测器模拟，事件重建和数据分析有益。
In this article we present the large photo-multiplier tube (PMT) afterpulse measurement results of Jiangmen Underground Neutrino Observatory (JUNO) experiment. Totally 11 dynode-PMTs (R12860) from Hamamatsu company and 150 micro-channel plate PMTs (MCP-PMTs, GDB-6201) from NNVT company were tested, an afterpulse model is built according to the afterpulse time distribution and probability of occurrence for these two types of PMTs. The average ratio between the total afterpulse charge with the delay between 0.5 $μ$ s and 20 $μ$ s to the primary pulse charge is 5.6%(13.2%) for the tested MCP-PMTs (dynode-PMTs). JUNO experiment will deploy 20,012 20-inch PMTs, and this study will benefit the detector simulation, event reconstruction and data analysis of JUNO experiment.
