Volume III. DUNE far detector technical coordination

Abstract

The preponderance of matter over antimatter in the early universe, the dynamics of the supernovae that produced the heavy elements necessary for life, and whether protons eventually decay—these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our universe, its current state, and its eventual fate. The Deep Underground Neutrino Experiment (DUNE) is an international world-class experiment dedicated to addressing these questions as it searches for leptonic charge-parity symmetry violation, stands ready to capture supernova neutrino bursts, and seeks to observe nucleon decay as a signature of a grand unified theory underlying the standard model. The DUNE far detector technical design report (TDR) describes the DUNE physics program and the technical designs of the single- and dual-phase DUNE liquid argon TPC far detector modules. Volume III of this TDR describes how the activities required to design, construct, fabricate, install, and commission the DUNE far detector modules are organized and managed. This volume details the organizational structures that will carry out and/or oversee the planned far detector activities safely, successfully, on time, and on budget. It presents overviews of the facilities, supporting infrastructure, and detectors for context, and it outlines the project-related functions and methodologies used by the DUNE technical coordination organization, focusing on the areas of integration engineering, technical reviews, quality assurance and control, and safety oversight. Because of its more advanced stage of development, functional examples presented in this volume focus primarily on the single-phase (SP) detector module.

Snowmass2021 Cosmic Frontier Dark Matter Direct Detection to the Neutrino Fog

“…The TPC is designed to take advantage of the favorable properties of liquid argon, including demonstrated electron recoil background discrimination power better than 10 8 [94] and excellent chemical purity [95,96], and operate with < 0.1 background events within the 20.2 t fiducial volume over a ten year run, other than an expected (3.2 ± 0.6) events from coherent neutrino scattering. The DS-20k experimental apparatus consists of three nested detectors installed within a membrane cryostat nearly identical to the two existing ProtoDUNE cryostats [97][98][99]: the inner two-phase argon TPC, a neutron veto, and an outer muon veto. The apparatus will be located in Hall C of the Gran Sasso National Laboratory (LNGS).…”

“…The data points are taken from the references [29;30] Chapter 2 DUNE and ProtoDUNE-SP Our current knowledge of particle physics does not explain some of the most intriguing questions in particle physics. The Deep Underground Neutrino Experiment (DUNE [32][33][34][35] ) is a leading-edge, international experiment for neutrino science and seeks to make groundbreaking discoveries to answer the following questions [6] :…”

Deep Learning Strategies for ProtoDUNE Raw Data Denoising

“…DUNE [7] is a next-generation experiment in the neutrino oscillation research field. The DUNE Far Detector (FD) [8][9][10], based at the Sanford Underground Research Facility (SURF) in South Dakota, will be the largest monolithic Liquid Argon Time Projecting Chamber (LArTPC) detector ever built. To test and validate technologies for the construction of such detector, a prototype, ProtoDUNE Single Phase (SP) [11], has been built at the CERN Neutrino Platform.…”
