DESCRIPTION:Speakers: Dmitry Svirida (Lebedev Physics Institute of RAS)\nD
 ANSS detector at Kalininskaya nuclear power plant demonstrates excellent p
 erformance in antineutrino detection. Counting rates of up to 5000 events 
 per day made it possible to record more than 6.5 million antineutrino even
 ts in 6 years of remarkably stable operation. The data sample is extremely
  clean and features the signal to background ratio in excess of 50. Yet on
 ly moderate energy resolution of 34% at 1 MeV limits the sensitivity of th
 e experiment for the sterile neutrino searches. \nThe upgrade of the detec
 tor is aimed at more than twice better energy resolution of 12% at 1 MeV. 
 Besides that the sensitive volume is planned to be increased by 70% inside
  the same shielded space on the lifting platform\, leading to almost twice
  higher the counting rate. New scintillation strips feature much better un
 iformity of the light collection. Readout from both strip edges provides i
 nformation on the longitudinal event coordinate. The talk will address the
  details and the status of the upgrade together with the latest results of
  beam tests. The expected influence of the improvements on the sensitivity
  to the sterile neutrino will also be discussed.\n\nhttps://indico.tlabs.a
