Joint Institute for Nuclear Research (JINR) initiated the creation of a new and unique heavy-ion collider – Nuclotron-based Ion Collider Facility (NICA), which is planned to be operational in 2016 [1]. The luminosity in the colliding beams of Au 79+ ions is expected to reach 10 27 cm -2 s -1 . By met estimates it will mainly be determined by the intra-beam scattering effect. To suppress one, it was proposed to use the cooling of the beam. For the medium and high-energy heavy ions, such as NICA collider, stochastic cooling will be more efficient, then electron cooling, so this system will be used in the collider. In the coming years it's planned to build stochastic cooling system prototype at presently working accelerator Nuclotron to test different working modes at an early stage of NICA project. Main results of the development of stochastic cooling system at Nuclotron are presented.
