DESCRIPTION:Speakers: Aleksanrd Mefodiev (INR RAS)\nThe long baseline neut
 rino experiments T2K has obtained a first hint on CP violation in neutrino
  oscillations and excluded CP conservation at the 95% confidence level. To
  strengthen this result the T2K collaboration is expected to collect the f
 ull exposure of 7.8×1021 protons on target\, thanks to planned upgrades t
 o the J-PARC and the neutrino beamline.   An upgrade of the T2K near detec
 tor ND280 has a goal to reduce a systematic uncertainty in the prediction 
 of number of events at the far detector   of less than 4%.   The project i
 ncludes the development of a new highly granular fully active scintillator
  neutrino detector as a neutrino target. This detector will allow us to ob
 tain   a much better uniformity of acceptance as a function of polar angle
 \, to reduce the threshold for detection of charged particles\, to improve
  the localization of the neutrino interaction vertex\, and to effectively 
 separate electrons from the neutrino interaction and background photons. T
 he baseline concept of a novel  highly granular fully active  detector wit
 h  dimensions of  ~200x180x60 cm3 and a total mass of about 2 tons will re
 present an array  of about 2x106 small scintillator cubes each of 1 cm3. E
 ach cube covered by a chemical reflector has three orthogonal cylindrical 
 holes of a 1.5 mm diameter. The signal readout from each cube is provided 
 by inserted in these holes three 1.0 mm Kuraray Y11 multiclad WLS fibers w
 hich connected to micro-pixel avalanche photodiodes MPPCs.  A prototype of
  this detector comprised of about 10000 cubes was tested in a beam of char
 ged particles (electrons\, muons\, pions\, protons) at CERN in 2018. Obtai
 ned parameters of the prototype: the light yield\, cross-talk\, and time r
 esolution will be presented.  The progress in R&D of this detector\, futur
 e plans to construct the full scale detectors and results of simulations w
 ill be also reported.\n\nhttps://indico.particle.mephi.ru/event/22/contrib
