论文摘要
深层中微子实验（Dune）是下一代长基线（1300 km）中微子振荡实验。中微子束测量将由近检测器（ND）和FAR检测器（FD）进行。 FAR检测器将由四个模块组成，这些模块安装在地下深1.5公里，基于液体氩时间投影室（LARTPC）技术来检测颗粒。垂直漂移（VD）LARTPC是Dune协作为第二FD模块提出的最新技术。在VD中，将通过将光子检测器嵌入LARTPC阴极中的光子探测器（以-300 kV为偏见）来优化光。结果，功率必须到达光子检测系统（PDS），并且信号必须通过非导电材料传输。提出的解决方案是使用电动纤维（POF）和信号纤维（SOF）。在CERN Neutmino平台的协作中，正在对系统进行强烈的验证，在2022年上半年收集的数据的设计和结果。
The Deep Underground Neutrino Experiment (DUNE) is a next generation long baseline (1300 km) neutrino oscillation experiment. The neutrino beam measurements will be performed by a near detector (ND) and far detector (FD). The far detector will consist of four modules, installed 1,5 km deep underground, based on Liquid Argon Time Projection Chamber (LArTPC) technology to detect particles. The Vertical Drift (VD) LArTPC is a recent technology proposed by the DUNE Collaboration for the second FD module. In VD, light collection will be optimized by embedding photon detectors within the LArTPC cathode, which is biased at -300 kV. As result, power must arrive to the Photon Detection System (PDS) and signal must be transmitted via non-conductive material. The proposed solution is to use Power-over-Fiber (PoF) and Signal-over-Fiber (SoF). An intense validation of the system is being performed by the Collaboration at the CERN Neutrino Platform, design and results from data collected over the first half of 2022 are presented.
