DUNEis a dual-site experiment for long-baseline
neutrino oscillation studies, neutrino astrophysics and nucleon
decay searches. ProtoDUNE Dual Phase (DP) is a
6×6×6m3 liquid argon time-projection-chamber (LArTPC)
that recorded cosmic-muon data at the CERN Neutrino Platform
in 2019–2020 as a prototype of the DUNE FarDetector.
Charged particles propagating through the LArTPC produce
ionization and scintillation light. The scintillation light signal
in these detectors can provide the trigger for non-beam
events. In addition, it adds precise timing capabilities and improves the calorimetry measurements. In ProtoDUNE-DP,
scintillation and electroluminescence light produced by cosmic
muons in the LArTPC is collected by photomultiplier
tubes placed up to 7m away from the ionizing track. In this
paper, the ProtoDUNE-DP photon detection system performance
is evaluated with a particular focus on the different
wavelength shifters, such as PEN and TPB, and the use of
Xe-doped LAr, considering its future use in giant LArTPCs.
The scintillation light production and propagation processes
are analyzed and a comparison of simulation to data is performed,
improving understanding of the liquid argon properties.CERN
