Light detection with power and signal transmission over fiber

Abstract The Deep Underground Neutrino Experiment is a next generation long baseline (1300 km) neutrino oscillation experiment. beam measurements will be performed by near detector and far detector. consist of four modules, installed 1.5 km deep underground, based on Liquid Argon Time Projection Chamber (LArTPC) technology to detect particles. Vertical Drift (VD) LArTPC recent proposed the DUNE collaboration for second FD module. In VD, light collection optimized embedding photon detectors within cathode, which biased at −300 kV. As result, power must arrive Photon Detection System signal transmitted via non-conductive material. solution use Power-over-Fiber Signal-over-Fiber. An intense validation system being CERN Platform. design results collected over first half 2022 are presented here.
