背景光子探测效率是高精度中微子和暗物质实验中光电倍增管的关键参数，而通常量子效率与归一化因子和角响应一起用作探测效率，其中它总是与来自校准归一化的探测器响应耦合。研究了20 ″光电倍增管在光子探测器中的绝对光子探测效率，为了更好地理解光子探测的物理过程，本文采用了量子效率和归一化因子相结合的方法结论不同光强下的相对量子效率和相对探测效率的测量结果基本一致，测量结果表明，当聚光灯位于PMT中心时，Hamamatsu R12860的聚光效率最高，而Hamamatsu R12199的聚光效率最低，R1355和HZC XP72B22在不确定度范围内具有相同的CE水平。讨论在入射光的配置和DE定义之后，我们可以进一步定义大面积PMT的DE，使用类似的算法，这也将用于JUNO中的探测器模拟。
Background Photon detection efficiency is a key parameter of PMTs in high-precision neutrino and dark matter experiments,while normally the quantum efficiency is used with a normalization factor and angular response as the detection efficiency,where it is always coupled with detector response from the calibration normalization.Here,the absolute photon detection efficiency of 20′′ PMTs in photon-counting level is further considered rather than the combination of quantum efficiency and normalization factors.Purpose and method In order to have a good understanding of photon detection efficiency of the large-area PMT,we conduct a detailed comparison of relative collection efficiencies of a series of PMTs with spotlight.This study is based on the tests of relative quantum efficiency and relative detection efficiency,checked with several light intensities.Conclusion All the results are consistent in relative QE and DE measurement with different light intensities,and the error of each parameter is coupled in our studies.Based on the measurements,Hamamatsu R12860 shows the maximum collection efficiency with spotlight at PMT center,and Hamamatsu R12199,R1355 and HZC XP72B22 have the same level of CE within the uncertainty.Discussion Following the configuration on incident light and DE definition,we can further define the DE of a large-area PMT with similar algorithms,which will also be used for detector simulation in JUNO.
