  NICA is the new complex being constructed on the JINR aimed to provide collider experiments with ions up to aurum at energy of 4.5x4.5 GeV/u. The NICA layout includes 600 MeV/u Booster synchrotron as a part of the injection chain of the NICA Collider. The main goals of the Booster are the following: accumulation of 4E109 Au31+ ions; acceleration of the heavy ions up to energy required for effective stripping; forming of the required beam emittance with electron cooling system. The layout makes it possible to place the Booster having 210.96 m circumference and four fold symmetry lattice inside the yoke of the former Synchrophasotron. The features of the Booster, its main systems, their parameters and current status are presented in this paper.

  Program complex for modelling of transverse dynamic of particle beams and orbit correction at Nuclotron synchrotron (LHEP JINR) is considered in current work. The program complex provides calculation of transverse dynamic of charged particle beams in Nuclotron and its axis, based on linear model with transport matrix of lattice elements, calculation of Nuclotron Twiss parameters, acceptance and emittance of the beam. A possibility to optimize the location of beam position monitors (pick-up) and multipole correctors is foreseen as well as calculation of the orbit with measuring data of pick-up stations of Nuclotron. Program complex includes realizations of orbit correction algorithms with response matrix and provides correction of the orbit in Nuclotron. User's graphic interface provides interaction of user with program complex, including performance on demand of the user of separate functions of the program complex, providing input and maintenance of parameters, download from file and record into the file of parameters and calculation results, graphical view of the calculations results in program complex. Program software environment is integrated with MAD-X program (upload, processing of data to and from, visualization). Format of input and output data is compatible with relevant MAD-X format.

  The results of modelling of ion's motion during beam slow extraction from Nuclotron at the energy 6 GeV/Amu are shown in this work. Influence of sextupole field component of dipole magnets and fringe fields of Lambertson's magnets on the characteristics of extracted beam was analyzed. The calculations have been done via MadX.

  Designs of systems of ion beam transfer from the linear accelerator HILAC into the Booster of the NICA accelerator complex (JINR, Dubna) including the transport beam line HILAC-Booster and the beam injection system of the Booster are considered in the report. The proposed systems provide multivariant 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, multiturn and multiple injection ones. Results of beam dynamics simulations are presented. Status of technical design and manufacturing of the systems' equipment is also highlighted.
