	The electron cooling system of the NICA booster is intended for accumulation of the ion beam at the injection energy and for cooling at some intermediate energy value before acceleration to the extraction energy. The system was produced in BINP (Novosibirsk, Russia) and commissioned in the JINR (Dubna, Russia) in 2019. The current status of the electron cooler and the results of its tests are presented in the article.

	The Nuclotron-based Ion Collider fAcility (NICA) project at the Joint Institute for Nuclear Research (JINR, Dubna, Russia), reached the phase of mounting and commissioning of the accelerator complex elements. The first stage of the project is "The Baryonic Matter at Nuclotron" (BM@N), fixed target experiment. It requires operation of the heavy ion synchrotron Booster, where electron cooler is used for formation of ion beam of a high intensity. One of limitation of intensity of partially ionized heavy ion beams is recombination with cooling electrons. This process is planned to be studied on the Booster, which is under mounting presently. The experiments at NICA collider with the heavy ion beams is the second stage of the project. High energy electron cooler that is under fabrication at BINP is a key tool for NICA collider allowing to reach the project luminosity in all ion energy range of (root)(s_NN) = 4 to 11 GeV/u. Recombination of bare nuclei of heavy ions in the electron cooler leads to significant beam losses that shorten ion life time and may generate considerable background in NICA detector (MultiPurpose Detector - MPD). The third stage is spin physics studies in collisions of polarized protons ((root)(s_NN)=27 GeV) and deuterons. This stage expect the use of the Spin Physics Detector - SPD. The report presents status of the NICA project development and discusses the problems described above.

	A feature of the NICA acceleration complex is high luminosity of colliding beams. Three types of RF stations will be used in the NICA Collider to reach the necessary beam parameters. The first one is for accumulation of particles in the longitudinal phase space with the moving barrier buckets under action of stochastic and/or electron cooling systems. The second and third RF stations are for formation of the final bunch size in the colliding regime. This report presents brief description of constructed in BINP three types of RF station and numerical simulations of longitudinal beam dynamics which take into account the longitudinal space charge effect, cooling and IBS during the accumulation and bunching procedures.
