DESCRIPTION:Speakers: Yury Kudenko ()\, Anna Dergacheva (INR)\nThe  long b
 aseline T2K neutrino experiment in Japan  obtained a  first indication of 
 CP violation  in neutrino oscillations. To obtain better sensitivity\, T2K
   will accumulate more statistics  with a higher intensity beam and the  u
 pgraded near detector ND280 which allows  us to reduce systematic uncertai
 nties in  oscillation measurements.  The upgraded detector will have the  
 full polar angle coverage for  muons produced in neutrino charged current 
 interactions\,  a low threshold for  proton detection and will be able to 
 measure neutrons using  time-of-flight due to a good timing performance.  
 Thanks to these new capabilities\,   the energy spectra of muon neutrinos 
 and antineutrinos  will be measured with an unprecedented  level of accura
 cy.  A  3D  highly granular scintillator detector  called SuperFGD with a 
 mass of about 2 tons  is being constructed at J-PARC now. It  consists of 
 about two millions of small optically-isolated plastic scintillator cubes 
 with a 1 cm side. Each cube is  read out in the three orthogonal direction
 s with wave-length shifting (WLS)  fibers coupled to  micro pixel photon c
 ounters (MPPC). All cubes are assembled in a light protected box with abou
 t 60000 holes for WLS fibers.  An LED calibration system  with Light Guide
  Plates is used for calibration and control for  WLS/MPPC readout. SuperFG
 D  Front End Board electronics based on CITIROC chips is developed and tes
 ted.  On-surface  SuperFGD will be provided with cosmic muons and  the ins
 tallation into the ND280 magnet is expected in September 2023  to take the
  neutrino  beam in the Fall of 2023. In this talk\, the  results of the te
 sts\, obtained parameters and  current status of SuperFGD   will be report
 ed. The unique features of SuperFGD  physics program will be also describe
