DESCRIPTION:Speakers: Yuri Koskin (NRNU MEPhI)\nCENNS-10 is a single phase
  liquid argon (LAr) scintillation detector deployed by the COHERENT collab
 oration at the Spallation Neutron Source located at the Oak Ridge National
  Laboratory in 2017. The detector was designed to study the Coherent Elast
 ic Neutrino-Nucleus Scattering (CEνNS) using the high-quality pion-decay-
 at-rest neutrino source. The collaboration reported the observation of CE
 νNS in LAr with CENNS-10 in 2020. After the science run\, a series of stu
 dies of LAr scintillation properties were performed. LAr as a scintillator
  produces 128 nm VUV light that lies well outside the reasonable sensitivi
 ty region of the most PMTs. Therefore\, wavelength shifters (WLS) are comm
 only used as a solution. CENNS-10 applies tetraphenyl-butadiene (TPB) coat
 ing on internal surfaces. It is known that xenon doping to LAr can act as 
 a volume-distributed WLS. To study the scintillation properties of various
  xenon-argon mixtures a dedicated engineering run was conducted with diffe
 rent xenon concentrations. Current status of the analysis and preliminary 
 results are discussed.\n\nhttps://indico.particle.mephi.ru/event/626/contr
