T12.00001: The MicroBooNE Continuous Readout Stream for the Detection of Supernova Core-collapse Neutrinos Iris Daniela Ponce-Pinto MicroBooNE is a liquid argon time projection chamber (LArTPC) neutrino experiment located on the Booster Neutrino Beamline (BNB) at Fermilab. MicroBooNE's primary research goals involve the study of BNB neutrinos and their interactions on argon. Its secondary goals involve astro-particle and exotic physics searches. Specifically, MicroBooNE is the first large-scale LArTPC operating with a continuous readout data stream dedicated to detecting neutrinos from a core-collapse supernova. To do so, MicroBooNE relies on an external SuperNova Early Warning System (SNEWS) alert, which comes with a latency on the order of hours, and prompts permanent storage of continuous readout data, otherwise written on a circular disk buffer. This talk will present the MicroBooNE continuous readout data stream, and studies performed to validate its successful operation and sensitivity to low-energy signatures consistent with supernova neutrino interactions in LArTPCs. |

T12.00002: Optical Readout for the ICARUS Cosmic Ray Tagger Tyler N Boone, Robert John Wilson The ICARUS Cosmic Ray Tagger is a vital subsystem to the ICARUS detector at the Fermilab Short-Baseline Neutrino program, providing rejection of signals that mimic neutrino events. The sides of the Tagger are being made with repurposed MINOS scintillator, but requires a new optical readout. The Colorado State University group has developed a readout system based in silicon photomultipliers, and will be producing them at their Fort Collins, Colorado facility. In this talk, we present the light yield requirements for the system and the final production design. |

T12.00004: The NOvA Test Beam Program Chatura D Kuruppu NOvA is a long-baseline neutrino oscillation experiment designed to precisely measure the neutrino mixing angles and to discover the neutrino mass hierarchy and probe leptonic CP violation by measuring the oscillation of muon (anti)neutrinos to electron (anti)neutrinos. A crucial measurable in the NOvA detectors is the neutrino energy Eν, which is the sum of leptonic energy (ELep) and hadronic energy (EHad). The systematic precision of Ev is dominated by the uncertainty in Ehad where NOvA has been observing a discrepancy between data and Monte Carlo simulation. Although the current NOvA oscillation measurements are dominated by statistics, it is essential to assess and mitigate the causes of systematic errors. Among the leading systematics on the latest measurement of the neutrino oscillation parameters by NOνA are calibration, detector response, and the muon and hadronic energy scales. This talk will describe how NOνA is deploying a scaled-down version of its detectors at the Fermilab Test Beam Facility (FTBF). The detector will be exposed to a new tertiary beam of pions, protons, muons, and electrons with known energies to address these issues and to help reduce systematic errors while providing a comprehensive cross-check of the NOvA calibration chain. |

T12.00005: Overview of ProtoDUNE Hannah Elizabeth Rogers The Deep Underground Neutrino Experiment (DUNE) is an international collaboration focused on studying neutrino oscillation over a long baseline (1300 km). DUNE will make use of a near detector and neutrino beam originating at the Fermi National Accelerator Laboratory outside of Chicago, IL and a far detector operating 1.5 km underground at the Sanford Underground Research Facility in South Dakota. The near and far detectors will use LArTPC (Liquid Argon Time Projection Chamber) technology to image neutrino interactions. The single-phase (LAr only) far-detector prototype, ProtoDUNE-SP, which contains 0.77 kilotonnes of LAr, is currently the largest single-phase LArTPC and has been in operation at CERN since September 2018. ProtoDUNE-SP acts as a test and validation of the design for the single-phase far detector, making use of one full-scale unit of the current far detector design. Data taken using a charged particle test beam and operation in a large cosmic flux enable the study of detector calibrations and optimization of event reconstruction algorithms. In this talk, I will give an overview of the construction, commissioning, and operation of ProtoDUNE-SP with an emphasis on first data analysis and critical detector calibrations, including calibration of space charge effects. |

T12.00006: Development of Diamond Muon Detectors for DUNE Nicholas Johnston for the DUNE collaboration The Deep Underground Neutrino Experiment is a long-baseline neutrino oscillation experiment currently under development, and will be highly sensitive to CP violation in neutrinos when it begins operation in the mid-2020s. The neutrino beam used by DUNE will be a horn-focused meson beam decaying to a neutrino and muon beam. Muons are easier to detect, which allows us to monitor the beam alignment, distribution, and intensity in real-time. I have built two prototype detectors in order to compare the performance of silicon and diamond ionization detectors in a neutrino beamline. This talk will focus on the testing of custom detectors in the NuMI beamline in order to validate the design and quantify their performance. |

T12.00007: DUNE 3DST near detector Jairo H Rodriguez Rondon for the DUNE collaboration The Deep Underground Neutrino Experiment (DUNE) is an international project with primary physics objectives to measurement the CP violation in the neutrino sector, proton decay and supernova neutrino bursts. DUNE will use the liquid argon time projection chamber technology (LArTPC). DUNE will be composed of two neutrino detectors exposed to the world’s most intense neutrino beam. The near detector will be placed ~ 574 meters from the neutrino source at Fermilab. The far detector will be located ~1300 km away and ~1.4 kilometres underground at the Sanford Underground Research Facility (SURF) in South Dakota. In this talk, we will focus on one of the DUNE near detector, a three-dimensional detector tracker called 3DST, which is a highly segmented plastic scintillator detector. With 3DST we expect to have a 4pi angle coverage for charged particles, as well as good energy and angular resolutions. Due to a fine granularity, 3DST is suitable for monitoring the beam profile and due to fast timing, it has great potential to measure neutron energy. |

T12.00008: Directional Detection of Fast Neutron Beam Backgrounds at SuperKEKB Jeffrey T Schueler SuperKEKB, the next generation upgrade to the KEKB accelerator facility in Tsukuba, Japan, employs a novel nano-beam scheme which focuses beams of colliding electrons and positrons to a vertical size of 50 nm at their interaction point (IP) to achieve a design luminosity of 8.0×1035 cm-2s-1; nearly 40 times higher than the previous world record set by KEKB. Tighter squeezed beams and increased luminosities lead to pernicious beam-induced backgrounds that must be properly understood and mitigated to ensure both the success and longevity of the Belle II detector that SuperKEKB produces collisions for. In this talk, we present a detection of the fast neutron background during the so called "Phase 2" of beam commissioning at SuperKEKB; the first data collection period with the Belle II detector in its final position at the IP. The fast neutron data used in this analysis was collected by a set of eight high resolution micro gas time projection chambers (μTPCs). These μTPCs reconstruct the detailed ionization distribution of individual nuclear recoils, allowing for unique directional capabilities such as measuring the directional distribution and energy spectra of neutron recoils. |

T12.00009: Progress status for the Mu2e calorimeter Gianantonio Pezzullo, Dexu Lin The Mu2e experiment at Fermilab searches for the charged-lepton flavor violating conversion of a negative µ into an e- in the field of an Al nucleus. The Mu2e goal is to improve by four orders of magnitude the current best limit on the search sensitivity. The main detector consists of a straw-tube tracker and a crystal calorimeter housed in a 1 T superconduction solenoid. The calorimeter plays a major role in providing particle identification capabilities, a fast online trigger filter, a seed for track reconstruction. The calorimeter design consists of two disks, each one made of 674 pure CsI crystals read by two arrays of UV-extended silicon photomultipliers (SiPMs). The first large-scale calorimeter prototype, the Module-0, was characterized with an electron beam in the energy range around 100 MeV at the Beam Test Facility in Frascati (Italy). Results of the test will be shown. We also report the results of the QA tests that have been made over the SiPMs and the crystals used for the final assembly. |
