Performance of Photon Detectors in ProtoDUNE

In preparation for physics with DUNE, the ProtoDUNE detector has collected data at CERN with beam momentum of 0.3, 0.5, 1, 2, 3, 6, and 7 GeV/c. Three types of photon-collecting methods are implemented in the single-phase module of ProtoDUNE; these modules (dip-coated light guides, double-shift light guides, and ARAPUCA) convert incident liquid argon scintillation photons into longer wavelengths to be recorded by SiPM detectors. ProtoDUNE data has been analyzed for its utility for physics analysis, including time and energy measurement and particle identification, by measuring the detection efficiency, stability, timing and energy resolution of the photon detectors.
