论文摘要
Hamamatsu R5912-02MOD光电塑料管（PMT）将用于Dune Duale Dual-phase模块，这是一个10 k型基准体积的液体 - 阿贡液体反射室，该室是Dune Long-Baseline Long-Baseline Long-Baseline Neutrino中性实验的四个投影远见模块之一。在沙丘双相模块中，液体氩气对位于14米低温恒温器底部的光检测器施加了高压。首次在4杆绝对压力和低温温度（在液氮中）测试了四个Hamamatsu R5912-02MOD PMT。没有任何机械或电损伤报告，可以验证在沙丘双相模块和其他大规模低温液体探测器中使用该PMT模型的使用。 PMT工作温度的变化期望在其行为中观察到的差异。
The Hamamatsu R5912-02Mod photomultiplier tube (PMT) will be used in the DUNE dual-phase module, a 10-kton fiducial volume liquid-argon time-projection chamber, which is one of the four projected far-detector modules of the DUNE long-baseline neutrino experiment. In the DUNE dual-phase module, the liquid argon places high pressure on the photo-detectors located at the bottom of the 14-m cryostat. Four Hamamatsu R5912-02Mod PMTs were tested at 4-bar absolute pressure and cryogenic temperature (in liquid nitrogen) for the first time. No mechanical or electrical damage is reported, validating the use of this PMT model in the DUNE dual-phase module and in other large scale cryogenic liquid detectors. The differences observed in their behavior are expected for the change in the PMT operating temperature.
