  The Nuclotron-based Ion Collider fAcility (NICA) is the new accelerator complex being constructed at JINR aimed to provide collider experiments with heavy ions up to uranium at the center of mass energy from 4 to 11 GeV/u. It includes 6 Mev/u linac, 600 MeV/u booster, upgraded SC synchrotron Nuclotron and collider consisting of two SC rings, which provide average luminosity of the level of 1027cm-2s-1.

  A schematic diagram of heavy ion injector based on laser ion sources is described. Two different basic laser configurations used in ITEP synchrotron. First laser excels in simplicity and consists of CO2 free-running laser that is applied for carbon target plasma heating and ionization at laser power density q=3·1012W/cm2 to create high current C4+ ion beam. Second master oscillator-amplifier (MOPA) laser configuration intends for production super high laser intensity at a target to provide considerable charge state in a plasma of heavy elements (Al, Fe, Ag etc). This laser configuration is founded on original physical principle* that simplifies the installation and ensures high reliability for long term operation. Laser characteristics for the different laser scheme and ion current for injector outlet beam of C4+ and Ag+19 are shown in this paper. The latter was accelerated in synchrotron for energy up to 100 MeV/u.

  The 'Nuclotron-M' project started in 2007 is considered as the key point of the first stage of the NICA/MPD project. General goal of the 'Nuclotron-M' project is to prepare all the systems of the Nuclotron for its long and reliable operation as a part of the NICA collider injection chain. Additionally the project realization will increase the Nuclotron ability for realization of its current experimental program. Results of the last runs of the Nuclotron operation are presented.

  The 7MeV/u 12C6+ ion beam was accumulated in CSRm,the ion beam accumulation dependence on the parameters of cooler was investigated experimentally. The 400MeV/u 12C6+ and 200MeV/u 129Xe54+ was stored and cooled in CSRe, the cooling force was measured in different condition. The ion beam bunch length and transverse size were roughly measured.

  TRIUMF started SCRF development with the superconducting heavy ion linear accelerator project, ISAC-II, in 2000. Since that time much work has been completed for development, prototyping and testing. The ISAC-II project was successfully completed and we now have in operation 40 superconducting bulk Nb QWR cavities assembled in eight cryomodules. The last twenty cavities, just completed, were produced by PAVAC Industries Inc. of Richmond BC; the first superconducting accelerator cavities produced in Canada. In 2007 TRIUMF started development towards a 50MeV electron superconducting linear accelerator to be used as a driver to produce radioactive ion beams through photofission. The accelerator is based on TTF/ILC elliptical bulk Nb cavities technology. Results, experience and plans of the SCRF program at TRIUMF will be discussed.
