DESCRIPTION:Speakers: Alicia Vázquez Ramos (University of Granada)\nThe S
 hort-Baseline Near Detector (SBND) is one of the three experiments in the 
 Short-Baseline Neutrino (SBN) Program at Fermilab. Located only 110 m down
 stream of the Booster Neutrino Beam (BNB) target\, SBND is the detector cl
 osest to the neutrino source. The detector is a Liquid Argon Time Projecti
 on Chamber (LArTPC) with a 112-ton active volume which enables unprecedent
 ed precision measurements of neutrino-nucleus interaction in liquid Argon.
  The detector began taking data in July 2024 and has already completed its
  first year of running. Its Photon Detection System (PDS) is a hybrid syst
 em consisting of 120 photomultiplier tubes (PMTs) and 192 novel X-ARAPUCA 
 devices\, accompanied by highly reflective panels coated with a wavelength
 -shifting compound covering the cathode and reflecting light towards the o
 ptical devices. An X-ARAPUCA functions as a light trap that captures photo
 n emitted by the Argon\, shifts their wavelength to a detectable spectrum 
 using a coating\, and then guides these photons to an array of silicon pho
 tomultipliers (SiPMs) for detection. The X-ARAPUCA system represents an R&
 D opportunity to demonstrate the performance of this novel technology in a
  LArTPC exposed to a neutrino beam over several years. There are two types
  of X-ARAPUCA installed: one sensitive to vacuum ultraviolet (VUV) argon s
 cintillation light and another sensitive to visible light. This talk prese
 nts an overview of the SBND detector\, focusing on its X-ARAPUCA system an
 d the path towards detecting the first X-ARAPUCA signals.\n\nhttps://indic
