“…DUNE is exploring this possibility because the xenon emission can be collected with higher efficiency due to its longer wavelength with respect to argon: 178 nm [13] instead of 127 nm. Furthermore, as it will be detailed later, the longer Rayleigh scattering length of the xenon photons in LAr [14] should enhance light collection far from the photon detectors [15]. Previous literature studies [16][17][18][19][20] have demonstrated the doping procedure in small scale detectors, and sometimes in gas phase.…”

DUNE is a dual-site experiment for long-baseline neutrino oscillation studies, neutrino astrophysics and nucleon decay searches. ProtoDUNE Dual Phase (DP) is a 6 $$\times $$ × 6 $$\times $$ × 6 m$$^3$$ 3 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 Far Detector. 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 7 m 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.

The DUNE experiment, currently under construction in the US, has a broad physics program that spans from oscillation physics at the GeV scale to the observation of solar neutrinos in few-MeV events. This program leverages the unprecedented resolution and imaging capability of the liquid argon TPC. LArTPCs are dense, fully-active detectors, that allow for a 3D real-time reconstruction of the events, achieved by means of the collection of drifted electrons from ionization. In addition to electrons, LArTPCs produce large quantities of VUV photons, which will be fully exploited in DUNE thanks to its Photon Detection System (PDS). The light collected by the PDS will be of paramount importance to measure the event timing and the vertical trajectory of charged particles for non-beam events, and will improve significantly the overall energy resolution of DUNE, especially at low energies, allowing to unlock its full scientific potential. The last few years marked important steps in the development of the PDS. Thanks to an intense R&D effort conducted at the two ProtoDUNE detectors at CERN, the PDS technology for DUNE has been optimized and validated for the DUNE physics. This article illustrates the concept of the DUNE PDS, its development and use in ProtoDUNE, as well as its role in achieving the physics goals of DUNE.

“…However, for larger volumes and more numerous photodetectors, such a method is impractical due to high memory requirements during data processing. Instead, a more robust method of calculating optical photon visibilty in LArTPCs based only on the relative position between the photodetector and point of scintillation was developed for the SBND [147]. Some version of this 'semi-analytic' method will likely be employed in DUNE.…”

In this paper, we review scientific opportunities and challenges related to detection and reconstruction of low-energy (less than 100 MeV) signatures in liquid argon time-projection chamber (LArTPC) neutrino detectors. LArTPC neutrino detectors designed for performing precise long-baseline oscillation measurements with GeV-scale accelerator neutrino beams also have unique sensitivity to a range of physics and astrophysics signatures via detection of event features at and below the few tens of MeV range. In addition, low-energy signatures are an integral part of GeV-scale accelerator neutrino interaction final-states, and their reconstruction can enhance the oscillation physics sensitivities of LArTPC experiments. New physics signals from accelerator and natural sources also generate diverse signatures in the low-energy range, and reconstruction of these signatures can increase the breadth of Beyond the Standard Model scenarios accessible in LArTPC-based searches. A variety of experimental and theory-related challenges remain to realizing this full range of potential benefits. Neutrino interaction cross-sections and other nuclear physics processes in argon relevant to sub-hundred-MeV LArTPC signatures are poorly understood, and improved theory and experimental measurements are needed; pion decay-at-rest sources and charged particle and neutron test beams are ideal facilities for improving this understanding. There are specific calibration needs in the low-energy range, as well as specific needs for control and understanding of radiological and cosmogenic backgrounds. Low-energy signatures, whether steady-state or part of a supernova burst or larger GeV-scale event topology, have specific triggering, DAQ and reconstruction requirements that must be addressed outside the scope of conventional GeV-scale data collection and analysis pathways. Novel concepts for future LArTPC technology that enhance low-energy capabilities should also be explored to help address these challenges.
