L03.00001: Properties of DUNE ND-GAr Readout Chambers Brandon Korb To probe neutrino oscillation physics, the Deep Underground Neutrino Experiment (DUNE) will have a near detector at Fermilab followed by a far detector which will be 1300 km away. The near detector consists of several subdetectors, including a high-pressure gaseous argon detector (ND-GAr). The goal of this project was to understand the properties of the readout chambers taken from A Large Ion Collider Experiment (ALICE) when used in high-pressure P10 gas for applications in the DUNE ND-GAr. This study focused on the gain in the avalanche region and the sag of the anode wires. To achieve this goal, Garfield++ and MagBoltz were used to simulate the chamber configuration and gas properties. Results will be presented on the expected performance of this chamber geometry with the anticipated DUNE gas configuration. [Preview Abstract] |

L03.00002: Simulated Electron Drift Properties in High Pressure Gaseous Argon Time Projection Chamber for the Deep Underground Neutrino Experiment Aaron Mutchler The Deep Underground Neutrino Experiment (DUNE) is a new cutting-edge experiment that will be fundamental in the study of neutrino oscillations and physics beyond the standard model. A crucial step in studying these oscillations is understanding the flux of neutrinos and their interaction cross sections in the near detector. This is done in a series of argon-based detectors. Neutrinos will interact with the argon and produce charged particles, which in turn liberate electrons which drift across the High Pressure Gaseous Argon Time Projection Chamber (HPgTPC). To extract the necessary information about neutrino interactions, details of the drift electrons must be known. Some of these details are drift velocity, diffusion, and attachment. This talk will give an overview of DUNE’s HPgTPC, introduce the simulation used to determine electron drift properties, and explore some of the requirements of the HPgTPC operating conditions.

L03.00003: Calorimetric Energy Measurement for Supernova Neutrinos using the DUNE Photon Detection System Biswaranjan Behera The photon detection system (PDS) is a subsystem of the Deep Underground Neutrino Experiment (DUNE). It measures the scintillation light signal and allows determination of the time of occurrence of an event of interest with much higher precision than charge collected from ionization in the liquid argon time-projection chambers and provides a complementary measurement of the deposited energy. This talk will report on simulation studies of calorimetric energy measurement of neutrinos from supernova neutrino bursts (SNB) in DUNE using the PDS. [Preview Abstract] |

L03.00004: A study of the effect of overburden on cosmogenic backgrounds in the Fermilab Short-Baseline Neutrino Program Far Detector (ICARUS) Anna Heggestuen When a cosmic ray muon collides with the upper atmosphere, it creates a shower of particles that transverse down to the Earth's surface. These cosmogenic particles provide a challenging background in neutrino experiments. The ICARUS detector is a Liquid Argon Time Projection Chamber (LArTPC) that is the far detector in the Short Baseline Neutrino (SBN) program, a program that is dedicated to resolve the sterile neutrino anomaly. As the ICARUS detector will operate at shallow depth, it is exposed to a high flux of these particles that could fake a neutrino interaction. The ICARUS detector is employing two techniques to mitigate this cosmogenic exposure: installing a 3-meter thick concrete overburden and a Cosmic Ray Tagging (CRT) System that will surround the detector medium and tag incoming particles. Using simulated data, one can study the effect of these two methods on rejecting the cosmogenic events. The effect of the concrete overburden is explored through simulation, where I study the effect the overburden has on stopping particles before they reach the cryostat. [Preview Abstract] |

L03.00005: Reducing Neutrino Flux Uncertainties Using Hadron Production Measurements at NA61/SHINE Kyle Allison Neutrino flux uncertainties are frequently a leading systematic uncertainty in current day measurements of neutrino oscillation parameters at long-baseline experiments. These uncertainties can be constrained by hadron production measurements performed by the NA61/SHINE experiment at CERN's Super Proton Synchrotron. NA61/SHINE analyzes the interactions of charged hadrons with materials relevant to long-baseline experiments to measure the differential cross sections of particles that contribute to neutrino flux. Measurements with thin and replica targets have also been taken by NA61/SHINE, and more measurements are planned for the upcoming years. [Preview Abstract] |

L03.00006: Installation of the ICARUS side Cosmic Ray Tagger Tyler Boone, Robert Wilson The ICARUS experiment requires a Cosmic Ray Tagger (CRT) to achieve sufficiently low backgrounds. I will present the status of the installation of the side CRT modules (~500 m$^2$) and the 2,680 channel readout electronics, along with the implications for running the full system.
