In the last years the Nuclotron-based Ion Collider fAcility (NICA) project is developed at Joint Institute for Nuclear Research (JINR), Dubna, Russia. Important elements of the NICA are two synchrotrons: Booster and Nuclotron. Connection between these synchrotrons is provided with the transfer channel for heavy ions at energy of 600 MeV/u. The transfer channel includes a stripping station and charge separation system. General goal of the optic design is to minimize emittance at the exit of the channel. Magnetic system of the channel will be constructed using magnets of the Nuclotron type.

Ions 197Au⁷⁸⁺ are generated in recombination of original bare nuclei 197Au⁷⁹⁺ with cooling electrons in the electron cooler of the NICA Collider. The ions 197Au⁷⁸⁺ dynamics is considered in the in energy range 1–4.5 GeV/u when ion beam is bunched with RF voltage (collision mode operation of the NICA Collider). It is shown that some part of 197Au⁷⁸⁺ ions can be involved in synchrotron motion when other part suffers a chaotic motion regime. Most of these ions live in vacuum chamber until further recombination in to the state of 197Au⁷⁷⁺ and leave the Collider acceptance very fast. The evolution in time of ion distribution over the Collider aperture is presented.

On the basis of experimental data the production of the ions Au⁷⁸⁺ and Au⁷⁷⁺ as a result of step-by-step radiative recombination of bare nuclei on free electrons in the NICA Collider electron cooling system is presented. The influence of Au⁷⁸⁺ ions on the luminosity lifetime is discussed. The optimum working cycle of the NICA Collider is described.

In the framework of the NICA project the new Booster lattice is designing. The NICA layout includes Electron String Ion Source, 3 Mev/u linac, 600 MeV/u booster synchrotron, upgraded Nuclotron and ion collider. The main goals of the Booster are the following: accumulation of 2*E9 Au³²⁺ ions; acceleration of the heavy ions up to energy required for effective stripping; forming of the required beam emittance with electron cooling system. The present layout makes it possible to place the Booster having 211 m circumference and four fold symmetry lattice inside the yoke of the Synchrophasotron. The features of this booster, the requirement to the main synchrotron systems and their parameters are presented in this paper.
