Search for neutrino oscillations at a research reactor

A project of search for oscillations of reactor neutrinos on a short, 5 - 15 meters, baseline with liquid scintillation position-sensitive detector POSEIDON is described. The oscillations of the electron antineutrinos into sterile neutrinos will be searched at 100 MW research reactor with the size of the active zone of about 0.5 m. The values of the oscillation parameters available for research are in the region $\delta m^2 = (0.3 - 6) \rm{eV}^2$ and $\rm{Sin}^2(2\theta)\geq 0.01$.
