论文摘要
在印度中微子天文台的Madurai的过境校园的Maduria校园的Maduria校园的Maduria校区的Maduriai的Maduriai校园中建造了一个宇宙MUON否决探测器（CMVD）。 CMV检测器将使用带有嵌入的波长转移（WLS）纤维的挤压塑料闪烁体制成，该纤维将较长波长的重新散发光子传播到硅光电材（SIPMS）。 SIPM检测到这些闪烁光子，产生电子信号。 CMV的宇宙MUON否决效率的设计目标是$> $ 99.99 \％\％和假否决税率小于10 $^{ - 5} $。使用LED驱动器开发了一个测试系统，以测量每个SIPM的噪声率和增益，从而确定其过电压（$ v_ {ov} $）。本文描述了测试结果和约3.5k sipms的分析特征。
A Cosmic Muon Veto Detector (CMVD) is being built around the mini-Iron Calorimeter (mini-ICAL) detector at the transit campus of the India based Neutrino Observatory, Madurai. The CMV detector will be made using extruded plastic scintillators with embedded wavelength shifting (WLS) fibres which propagate re-emitted photons of longer wavelengths to silicon photo-multipliers (SiPMs). The SiPMs detect these scintillation photons, producing electronic signals. The design goal for the cosmic muon veto efficiency of the CMV is $>$99.99\% and fake veto rate less than 10$^{-5}$. A testing system was developed, using an LED driver, to measure the noise rate and gain of each SiPM, and thus determine its overvoltage ($V_{ov}$). This paper describes the test results and the analysed characteristics of about 3.5k SiPMs.
