DESCRIPTION:Speakers: Niccolo' Gallice (Università degli Studi di Milano 
 - INFN Milano)\nThe Deep Underground Neutrino Experiment (DUNE) will be th
 e next generation long-baseline neutrino experiment. The far detector is d
 esigned as a complex of four LAr-TPC (Liquid Argon Time Projection Chamber
 ) modules with 17 t of LAr  each. The development and validation of its te
 chnology is pursued through ProtoDUNE Single Phase (ProtoDUNE-SP)\, a 770 
 t LAr-TPC at CERN Neutrino Platform. Crucial in DUNE is the Photon Detecti
 on System that will enable the trigger of non-beam events - proton decay\,
  supernova neutrino burst\, solar neutrinos and BSM searches - and will im
 prove the timing and calorimetry for neutrino beam events. Doping Liquid A
 rgon (LAr) with Xenon is a well known technique to shift the light emitted
  by Argon (128 nm) to a longer wavelength (175 nm) to ease its detection. 
 The largest Xenon doping test ever performed in a LArTPC was carried out i
 n ProtoDUNE-SP. From February to May 2020\, a gradually increasing amount 
 of Xenon was injected to compensate for the light loss due to air contamin
 ation. The response of such a large TPC (770 t of Liquid Argon and 440 t o
 f fiducial mass) has been studied using the ProtoDUNE-SP Photon Detection 
 System (PDS) and a dedicated setup installed before the run.\nHere we intr
 oduce the Xenon doping technique as well as the specific detector componen
 ts developed for this campaign and the results of the study with particula
 r regard to the modification of the scintillation signal\, the uniformity 
 of the light collection and the efficiency of the wavelength-shifting mech
 anism.\n\nhttps://indico.physics.ucsd.edu/event/1/contributions/16/
