Designs of systems of ion beam transfer from the linear accelerator HILAC into the Booster of the NICA accelerator complex (JINR, Dubna) [1] including the transport beam line HILAC-Booster and the beam injection system of the Booster are considered in the report. The proposed systems provide multi-variant injection for accumulation of beams in the Booster with required intensity. Special attention is paid to various aspects of beam dynamics during its transfer. Main methods of beam injection into the Booster are described. These are single-turn, multi-turn and multiple injection ones. Results of beam dynamics simulations are presented. Status of technical design and manufacturing of the systems' equipment is also highlighted.
