Nuclotron-based Ion Collider fAcility (NICA) is the new accelerator complex being constructed at the JINR. It includes the injection complex, existing superconducting proton synchrotron "Nuclotron", and the new superconducting proton synchrotrons – the Booster and the Collider. We plan to use in the NICA several cooling systems: electron cooling for the Booster and for the Collider, and stochastic cooling for the Collider. The Booster electron cooling system is designed for the electron energy range of 1.5 – 60 keV and maximum current of 1.0 A. The elements of electron cooling system (electron gun, collector, power supply system) will be tested at the test-bench "Recuperator" at the JINR. In the report the design and the basic parameters of the Booster electron cooling system are presented.

The homogeneity of the magnetic field in the straight solenoid of the electron cooling system is the very important task. The superconducting solenoids are planned for electron cooling systems of collider rings of NICA project. To reach the necessary homogeneity in the straight section the superconducting shield was proposed. The experimental and numerical investigations of the field homogeneity with the superconducting shield are presented.

The electron cooling system at electron energy up to 2.5 MeV for the NICA collider is under design at JINR. The electron cooler is developed according to the available world practice of similar systems manufacturing. The main peculiarity of the electron cooler for the NICA collider is using of two cooling electron beams (one electron beam per each ring of the collider) that never has been done before. The acceleration and deceleration of the electron beams is produced by common high-voltage generator. The conceptual design of the electron cooling system has been developed. The cooler consist of three tanks. Two of them contain acceleration/deceleration tubes and are immersed in superconducting solenoids. The third one contains HV generator, which design is based on voltage multiplying scheme
