DESCRIPTION:Speakers: Anatolii Serebrov (PNPI NRC KI)\nIn connection with 
 the question of possible existence of sterile neutrino the laboratory on t
 he basis of SM-3 reactor (Dimitrovgrad\, Russia) was created to search for
  oscillations of reactor antineutrino. In the middle of 2015 the multisect
 ion prototype of a neutrino detector with liquid scintillator volume of 35
 0 l was installed. It can be moved at the distance of 6-11 m from the reac
 tor core inside passive shielding. For the first time the measurement of t
 he reactor antineutrino flux dependence at so short distances from the rea
 ctor core center with movable detector was realized. Different methods of 
 cosmic background suppression were studied. After half year collecting sta
 tistics the accuracy of measurements of first point at 6.5 m is 10%. The f
 ull-scale detector with volume of liquid scintillator 3 m$^{3}$ (5$\\times
 $10 section) is in the stage of preparation. It will allow obtaining the s
 tatistic accuracy of measurements at 6-11 m up to 1.5 – 3.0 % after 2 ye
 ars of measurements.\n\nhttps://indico.particle.mephi.ru/event/4/contribut
