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.
