  In order to carry out research in the field of possible existence of a
sterile neutrino the laboratory based on SM-3 reactor (Dimitrovgrad, Russia)
was created to search for oscillations of reactor antineutrino. The prototype
of a multi-section neutrino detector with liquid scintillator volume of 350 l
was installed in the middle of 2015. It is a moveable inside the passive
shielding detector, which can be set at distance range from 6 to 11 meters from
the reactor core. Measurements of antineutrino flux at such short distances
from the reactor core are carried out with moveable detector for the first
time. The measurements with full-scale detector with liquid scintillator volume
of 3 m^3 (5x10 sections) was started only in June, 2016. The today available
data is presented in the article.
