DESCRIPTION:Speakers: Jacopo Dalmasson (Stanford University)\nOne of the i
 mportant variables to optimize for a successful detection of the neutrinol
 ess double-beta decay is the energy resolution at its Q-value. nEXO is a p
 roposed tonne-scale experiment aiming to search such decay for the isotope
  Xe-136. It exploits the anticorrelation between ionization and scintillat
 ion of xenon to improve the ultimate energy resolution. A major factor aff
 ecting the resolution is the fluctuation of charge and light ultimately co
 llected.\nIn a time projection chamber (TPC) detector\, the electron colle
 ction efficiency is usually close to one. Conversely\, the collection of p
 hotons can vary dramatically depending\, along with other factors\, on the
  overall light-sensitive area of the detector.\nThe Stanford liquid xenon 
 TPC is a teststand planning to host the first VUV large area (~200cm2) SiP
 M array. The setup firstly aims to study the feasibility of such system wi
 th dedicated readout electronics and ultimately to investigate how a bette
 r light collection affects the detector performances\, important prototypi
 ng step for nEXO.\nIn this talk\, I will report on the status of the assem
 bly of this photodetector array\, along with characterization measurements
  and comparison with simulation.\n\nhttps://indico.physics.ucsd.edu/event/
