Present status of sensitive detector of reactor's antineutrinos using scintillating detectors

Popis výsledku v původním jazyce

In 2011, the reanalysis of the reactor antineutrinos spectra led to the formulation of the Reactor Antineutrino Anomaly (RAA), which indicates the discrepancy between measured and expected antineutrino fluxes on short baselines. This discrepancy appears to favor the existence of the fourth "sterile" neutrino with |delta m2| > 1 eV2. To confirm or reject this hypothesis a high sensitive antineutrino detector located close to the reactor is required. In addition to that such a detector could be used to online monitor the isotopic composition of the reactor core and to prevent illegal production and removal of 239Pu, which is the essential part of nuclear weapons. Detector DANSSino already proved that even a compact antineutrino detector (1m3) based on polystyrene is capable of antineutrino detection in the close vicinity of a reactor core (10 m) with signal to background ratio about one. As a common activity between JINR Dubna and IEAP CTU a new prototype of detector (called S3) has been proposed and is under construction. The construction design, selected results of Monte Carlo simulations and results of benchmark tests are presented.
