DESCRIPTION:Speakers: Gleb Erofeev (INR RAS)\nHyper-Kamiokande is a new ge
 neration of 260 kiloton water Cherenkov detector\, construction of which b
 egan in 2020. One of the main goals is to search for CP symmetry violation
  in neutrino oscillations. Hyper-Kamiokande is divided into internal and o
 uter detectors\, which are equipped with photomultiplier tubes (PMT). The 
 outer detector (OD) is used as a veto system for incoming charged particle
 s\, mainly muons. In OD\, Cherenkov radiation is detected by photomultipli
 ers with a diameter of 8 cm and wavelenght-shifting (WLS) plates\, which c
 over the “dead” space between the photomultipliers and thereby increas
 e the light collection area of OD and increase the efficiency of detecting
  background events. In total\, it is planned to use about 3600 photomultip
 liers in combination with WLS plates in the Hyper-Kamiokande outer detecto
 r. Light from Cherenkov radiation will hit the plates\, be absorbed and th
 en re-emitted in accordance with the relationship between the emission and
  absorption spectra of the material used. The report will present the resu
 lts of a study of parameters of WLS plates and a method for quick tests an
 d control their quality.\n\nhttps://indico.particle.mephi.ru/event/436/con
