DESCRIPTION:Speakers: Alejandro Sánchez Castillo (Universidad de Granada)
 \nSBND is a Liquid Argon Time Projection Chamber (LArTPC)\, serving as the
  near detector of the Short Baseline Neutrino program at Fermilab. Its nea
 r location (110 m) to the neutrino source and relatively large mass (112 t
 on active volume) will allow studying neutrino interactions on argon with 
 unprecedented precision. The detector is currently finishing the commissio
 ning phase and has collected its initial neutrino beam data. The Photon De
 tection System (PDS) of the detector represents a major R&D opportunity fo
 r the LArTPC technology. Its design is a hybrid concept combining a primar
 y system of 120 photomultiplier tubes (PMTs)\, and a secondary system of 1
 92 XARAPUCA devices\, all of them located behind the anode plane. Furtherm
 ore\, covering the cathode plane with highly reflective panels coated with
  a wavelength shifting compound recovers part of the light emitted towards
  the cathode\, where no optical detectors exist. This new design provides 
 high light-yield and more uniform detection efficiency\, an excellent time
  resolution and an independent position reconstruction (including the drif
 t coordinate) using only the scintillation light. This work will present t
 he first steps towards the calibration of the PMT devices\, which is criti
 cal to exploit the reconstruction capabilities of this system.\n\nhttps://
