Title: Using the Whole Buffalo: Coordinating Subsystems of the DUNE Far Detector prototype for a measurement of light attenuation in liquid argon


The Deep Underground Neutrino Experiment (DUNE) is a future accelerator-based multi-detector neutrino experiment currently in development by an international collaboration of scientists and to be hosted simultaneously at Fermilab and the Sanford Underground Research Facility. Upon activation, DUNE will investigate a number of fundamental questions about our universe using neutrinos and their ability oscillate in flavor over long baselines, including explanations of the matter/anti-matter asymmetry. The DUNE Far Detector will also be sensitive to the abundance of neutrino signals from supernova bursts and the very faint signals of proton-decay. In the Fall of 2018, the first in a pair of full-scale prototypes of the DUNE-Far Detector known as ProtoDUNE-Single Phase was activated. The prototype detector was configured to observe beam particles from the proton injector to the LHC, however cosmic-ray events are also present and can provide important information about the active volume. This talk will discuss the commissioning and performance of the prototype detector, the capture and reconstruction of cosmic-ray muons, and a novel analysis developed to measure the Rayleigh scattering length, a component of attenuation for scintillated light in liquid argon.
