The SIS100 heavy ion synchrotron, the core machine of the FAIR complex, uses fast ramped superconducting magnets. As for its ancestor, the Nuclotron operational at JINR Dubna since 1993, its superconducting magnets are based on iron dominated design and coils made of Nuclotron type cables. The SIS100 magnets differ from the Nuclotron magnets in the following points: they are longer, the field aperture was enlarged and the field quality improved, its AC losses reduced. The coils have a lower hydraulic resistance and the operation current is doubled. These achievements were obtained in a R&D collaboration between JINR and GSI. Now in the realization phase GSI will procure and test the SIS100 dipole magnets, while JINR together with GSI will finalize the design of the quadrupoles units (consisting of one quadrupole and one corrector), procure, test and assemble them into doublets. We report on the status of the project, the scheme of the JINR-GSI collaboration for developing and manufacturing the SIS100 quadrupole modules and the steps required to achieve the start of the series production.

NICA is a new accelerator complex being under design and construction at Joint Institute for Nuclear Research in Dubna. The actual design and the main characteristics of superconducting magnets for the NICA booster and the NICA collider are given. The magnets are based on a cold window frame iron yoke and a single-layered superconducting winding made from a hollow NbTi composite superconductor cable cooled with forced two-phase helium flow. The first results of cryogenic tests of the magnets for the NICA project are presented.

Accelerator complex NICA, developed in VBLHEP JINR, must provide an ion-ion (Au79 +) and ion-proton collisions at energies of 1-4.5 GeV/u, as well as experiments on collisions of polarized proton-proton and deuteron-deuteron beams. The calculations of the optical properties of superconducting collider rings have been aimed to create appropriate conditions for the collisions of beams and obtaining the required luminosity parameters in the working range of energies. The collider characteristics and the beam dynamics have been worked out in most for ion-ion mode of the complex.

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.

Development of the automatic control vacuum system (ACVS) for NICA project was beginning. The first step of this work was Nuclotron vacuum system modernization. It were installed new vacuum pumps and gauges with RS-232, RS-485 and ProfiBus interfaces. Devices were combined to the net with central controller at Linac control room. The result of the modernization was creation of remote control, monitoring and automatic protective system. Next step of ACVS creation will be Linac vacuum system automatization. Experience of the Nuclotron vacuum system modernization will be applied for NICA ACVS development.
