“…The main focus of the doping campaign in ProtoDUNE was indeed to evaluate its feasibility and the advantages for the DUNE Far Detectors in a real, large-scale set up. Furthermore, boosting the doping at the level of a few percent could enhance the physics goals of DUNE, making one of the far detector modules a next-generation, neutrinoless double beta decay experiment [31].…”

Doping of liquid argon TPCs (LArTPCs) with a small concentration of xenon is a technique for light-shifting and facilitates the detection of the liquid argon scintillation light. In this paper, we present the results of the first doping test ever performed in a kiloton-scale LArTPC. From February to May 2020, we carried out this special run in the single-phase DUNE Far Detector prototype (ProtoDUNE-SP) at CERN, featuring 720 t of total liquid argon mass with 410 t of fiducial mass. A 5.4 ppm nitrogen contamination was present during the xenon doping campaign. The goal of the run was to measure the light and charge response of the detector to the addition of xenon, up to a concentration of 18.8 ppm. The main purpose was to test the possibility for reduction of non-uniformities in light collection, caused by deployment of photon detectors only within the anode planes. Light collection was analysed as a function of the xenon concentration, by using the pre-existing photon detection system (PDS) of ProtoDUNE-SP and an additional smaller set-up installed specifically for this run. In this paper we first summarize our current understanding of the argon-xenon energy transfer process and the impact of the presence of nitrogen in argon with and without xenon dopant. We then describe the key elements of ProtoDUNE-SP and the injection method deployed. Two dedicated photon detectors were able to collect the light produced by xenon and the total light. The ratio of these components was measured to be about 0.65 as 18.8 ppm of xenon were injected. We performed studies of the collection efficiency as a function of the distance between tracks and light detectors, demonstrating enhanced uniformity of response for the anode-mounted PDS. We also show that xenon doping can substantially recover light losses due to contamination of the liquid argon by nitrogen.

“…Phase II, which completes the full DUNE scope, and includes upgrades to at least 40-kt of far detector fiducial mass, a 2.4 MW proton beam, and the full near detector, is critical for both the oscillation and non-oscillation physics programs of DUNE. Additionally, each of the Phase II upgrade components also provides an opportunity to broaden DUNE's physics portfolio to address additional science drivers and to therefore involve a wider community, including potential opportunities for dark matter detection, neutrinoless double-beta decay measurements [12], and additional BSM searches. There is also significant community interest in other experimental efforts that may make use of Fermilab's upgraded proton accelerator complex [13].…”

“…Collecting 50% of the scintillation light in a large LArTPC is challenging due to the large detector size, isotropic emission, and the requirement to wavelength shift the light. A different concept has been proposed in Refs [17] and [18], which is to dope the LAr with a photosensitive dopant [19,20], which directly converts the isotropic scintillation signal to a directional ionization signal with high efficiency, with estimates up to 60% [19]. Recently, the capabilities of LArTPCs with extended MeVscale energy resolution have been explored, and it has been found that LArTPCs could, with a few R&D advances, reach normal-ordering sensitivity to neutrinoless double-beta decay with xenon doping and the introduction of these photosensitive dopants [17].…”

“…The introduction of photosensitive dopants would lead to an enhanced ionization signal, especially where scintillation signals are large. This is expected to improve the energy reconstruction of lowenergy signals [16,17]. It would also lead to a more linear detector response for highly quenched processes.…”

“…With several of the exciting enabling technologies described above-underground argon for very low radioactivity, photo-ionizing dopants, and xenon doping in LArTPCs-there is the possibility of performing an extremely sensitive neutrinoless double beta decay search in a DUNE module, as described by Mastbaum, Pshihas, and Zennamo in Ref. [17]. The photo-ionizing dopants improve the energy resolution substantially over exclusive primary ionization and direct photon detection, and by re-using a DUNE module infrastructure costs would be dramatically lower than an entirely new detector.…”

Neutrino physics spans an enormous range of energies and scales: from detection of low-energy cosmic neutrinos; to keV-scale recoils in coherent neutrino scattering; to MeV-scale solar, reactor, and neutrinoless double beta decay events; to GeV and TeV-scale detection of neutrinos from accelerators and the atmosphere; to cosmic sources in the PeV-ZeV range. While any particular experiment tends to focus on just one or two detection approaches, the great breadth of neutrino physics means that there is an equally broad spectrum of neutrino detection technologies and methodologies.At any one time, there are a dozen or more medium-to large-scale neutrino detectors operating worldwide, several more in the design or construction phases, and many future detectors planned. Beyond this are a diverse set of smaller scale prototypes distributed across universities and labs.The focus in this report is on new technologies and approaches that will enable future neutrino detectors, and thus experiments that are already built and running, are under construction, or for which technical designs exist are not discussed in great detail. Recommendations for Next-Generation Neutrino DetectorsWhile there are many exciting detectors and enabling technologies described in this report, there are a few ideas that have had a particularly large community interest, and we formulate these into a set of recommendations below: 1 Future Advances in Photon-Based Neutrino Detectors arXiv:2203.07479 2 Coherent elastic neutrino-nucleus scattering: Terrestrial and astrophysical applications arXiv:2203.07361 3 Recoil imaging for dark matter, neutrinos, and physics beyond the Standard Model arXiv:2203.05914 4 Low-Energy Physics in Neutrino LArTPCs arXiv:2203.00740 5 SoLAr: Solar Neutrinos in Liquid Argon arXiv:2203.07501 6 Low Background kTon-Scale Liquid Argon Time Projection Chambers arXiv:2203.08821 7 Measuring the Neutrino Event Time in Liquid Argon by a Post-Reconstruction One-parameter Fit
