“…Most of the nonlinearity was then removed. The intercept of the linear fit after correction indicates an energy offset of -56 ± 14 MeV, in better agreement with the expected beam electron energy loss in the materials before entering the TPC -details of this study can be found in [67]. Based on the linearity of the light response, the relative calorimetric energy resolution 𝜎 𝐸 /𝐸 e is obtained from the 𝜎 𝑁 /𝑁 Ph ratio of the light response (figure 70 -right).…”

“…Since the energy loss occurs downstream of the momentum spectrometer, this energy degradation and its fluctuation do not appear in the incident beam energy spectra and it is evaluated by simulations (∼ 2%). Other contributions to the resolution, such as non-uniformity on the detector illumination, channel to channel response variation and possible shower leakage across the cathode, have been investigated and shown to be negligible [67]. The light yield and resolution response obtained from a single ARAPUCA module is adequate.…”

First results on ProtoDUNE-SP liquid argon time projection chamber performance from a beam test at the CERN Neutrino Platform

The ProtoDUNE-SP detector is a single-phase liquid argon time projection chamber with an active volume of 7.2× 6.1× 7.0 m3. It is installed at the CERN Neutrino Platform in a specially-constructed beam that delivers charged pions, kaons, protons, muons and electrons with momenta in the range 0.3 GeV/c to 7 GeV/c. Beam line instrumentation provides accurate momentum measurements and particle identification. The ProtoDUNE-SP detector is a prototype for the first far detector module of the Deep Underground Neutrino Experiment, and it incorporates full-size components as designed for that module. This paper describes the beam line, the time projection chamber, the photon detectors, the cosmic-ray tagger, the signal processing and particle reconstruction. It presents the first results on ProtoDUNE-SP's performance, including noise and gain measurements, dE/dx calibration for muons, protons, pions and electrons, drift electron lifetime measurements, and photon detector noise, signal sensitivity and time resolution measurements. The measured values meet or exceed the specifications for the DUNE far detector, in several cases by large margins. ProtoDUNE-SP's successful operation starting in 2018 and its production of large samples of high-quality data demonstrate the effectiveness of the single-phase far detector design.

“…On the other hand, charge-selective contact devices [6] follow a three-layer structure, including a thin layer of metal oxides where hole mobility exceeds electron mobility (MoO 𝑥 or WO), a thick layer of intrinsic a-Si:H, and a thin layer of a metal oxide where electron mobility is greater than hole mobility (such as TiO 2 or Aluminum-doped Zinc Oxide).…”

Hydrogenated amorphous silicon (a-Si:H) is a material with a very good radiation hardness and with the possibility of deposition on flexible substrates like Polyimide (PI). Exploiting these properties, the HASPIDE (Hydrogenated Amorphous Silicon PIxels DEtectors) project has the goal of developing a-Si:H detectors on flexible substrates for beam dosimetry and profile monitoring, neutron detection and space experiments. The detectors for this experiment will be developed in two different structures: the n-i-p diode structure, which has been used up to now for the construction of the planar a-Si:H detectors, and the recently developed charge selective contact structure. In the latter the doped layers (n or p) are replaced with charge selective materials namely electron-selective conductive metal-oxides (TiO2 or Al:ZnO) and hole-selective conductive metal oxides (MoO x ). In this paper preliminary data on the capabilities of these detectors to measure X-ray and electron fluxes will be presented. In particular, the linearity, the sensitivity, the stability and dark current in various conditions will be discussed.

“…The Deep Underground Neutrino Experiment (DUNE) promises one of the largest highly instrumented fiducial detector masses of any future large underground facility [461,462]. With 40 kt of liquid argon (LAr) some 1500 m below Lead, South Dakota to shield against cosmic ray backgrounds, DUNE's immense wire readout particle ionization charge-collection system across four separate modules forms its three-dimensional LAr time projection chambers, allowing scientists to exploit bubble-chamber quality images [463][464][465] for world-leading precision physics studies of the SM and beyond. With potentially MeV-scale precision [466], the ability to distinguish γ and e species [467], low cosmic µ backgrounds, and very low LAr ionization kinetic energy thresholds for even heavy charged species such as protons (ps) [57,462], the overall physics potential of DUNE goes far beyond its initial purpose as a ν detector built to better constrain and measure oscillation parameters such as δ CP .…”

Searches for Baryon Number Violation in Neutrino Experiments: A White Paper

Baryon number conservation is not guaranteed by any fundamental symmetry within the Standard Model, and therefore has been a subject of experimental and theoretical scrutiny for decades. So far, no evidence for baryon number violation has been observed. Large underground detectors have long been used for both neutrino detection and searches for baryon number violating processes. The next generation of large neutrino detectors will seek to improve upon the limits set by past and current experiments and will cover a range of lifetimes predicted by several Grand Unified Theories. In this White Paper, we summarize theoretical motivations and experimental aspects of searches for baryon number violation in neutrino experiments.
