  Since last RuPAC two runs of the Nuclotron operation were performed: in January - March of 2015 and June 2016. Presently we are providing the run, which has been started at the end of October and will be continued up to the end of December. The facility development is aimed to the performance increase for current physical program realization and preparation to the NICA Booster construction and Baryonic Matter at Nuclotron experiment.

  The new accelerator complex Nuclotron-based Ion Collider fAcility (NICA) is now under development and construction at JINR, Dubna. This complex is assumed to operate using two injectors: modernized old Alvarez-type linac LU-20 as injector of light polarized ions and a new Heavy Ion Linear Accelerator HILAc - injector of heavy ions beams. The new heavy ion linac accelerate ions with q/A values above 0.16 to 3.2 MeV/u is under commissioning. The main components are 4-Rod-RFQ and two IH - drift tube cavities is operated at 100.6 MHz. Main results of the HILAc commissioning with carbon beam from the laser ion source are discussed.

  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.

  The Nuclotron-based Ion Collider fAcility (NICA) - accelerator complex is being constructed at JINR. It is aimed to the collider experiments with ions and protons and has to provide the ion-ion (Au+79) and ion-proton collision in the energy range of 1-4.5 GeV/amu and also polarized proton-proton and deuteron-deuteron collisions. Each of two collider ring has a racetrack shape with two bending arcs and two long straight sections. Beams are separated in vertical plane and come into collisions in two IPs. Dynamic aperture of the NICA collider has been studied for different parameters of the optics at IP. Effects of the fringe fields of structural elements are considered in the optimization of the collider lattice.
