  Status of the project of Nuclotron-based Ion Collider fAcility NICA/MPD (MultiPurpose Detector) under development at JINR (Dubna) is presented. The general goals of the project are providing of colliding beams for experimental studies of both hot and dense strongly interacting baryonic matter and search for the mixed phase and critical endpoint. Spin physics experimental studies in collisions of polarized protons (deuterons) are planned as the second stage of the project. The first program requires providing of heavy ion collisions in the energy range of squrt(s) = 4-11 GeV at average luminosity of L = 1·1027 cm-2 s-1 for Au79+. The polarized beams mode is proposed to be used in energy range of squart(s) = 12-27 GeV (protons) at luminosity of L = 1·1030 cm-2 s-1. The key issue of the project is application of both stochastic and electron cooling methods at the NICA collider. The latter will be used in the NICA Booster for preliminary formation of the ion beam. The report contains description of the facility scheme and characteristics in heavy ion operation mode, the discussion of luminosity life time limitations, status and plans of the project development.

  A 2 MeV electron cooling device will be installed at COSY in order to boost the luminosity of pellet target experiments. The magnetized electron cooling technique is used to compensate the energy loss and emittance growth for future COSY pellet target experiments. In this article, a numerical simulation of cooling process is performed with BETACOOL code. The cooling time is calculated for variant cooler setting parameters. The intrabeam scattering (IBS) and target effect are essential for prediction of equilibrium beam parameters. The influence of the pellet target on the beam parameters is demonstrated.
