  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.

 Transport Beam Lines, Beam Injection and Extraction Systems at NICA Accelerator Complex  
 
  • A. Tuzikov
    JINR, Dubna, Moscow Region, Russia
  
  New accelerator complex is constructed by Joint Institute for Nuclear Research (Dubna, Russia) in frame of Nuclotron-based Ion Collider fAcility (NICA) project. Transport beam lines and systems of beam injection/extraction into/from the NICA synchrotrons and the Collider rings are the important link for the whole accelerator facility. Designs and current status of main beam transfer systems of the NICA complex are presented in this paper.

  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.

  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.

THPSC013 The Nonsymmetrical Variant of the Nonferromagnetic Extraction Kicker Magnet of the NICA Booster 566

    JINR, Dubna, Moscow Region, Russia
  
  Development and creation of the NICA acceleration complex are continued at JINR (Dubna). One of the main facilities of the complex is the Booster in which preliminary acceleration and cooling of an ion beam is performed. Further acceleration is fulfilled in the circular accelerator NUCLOTRON. The beam transfer from the Booster into the NUCLOTRON is provided by means of the fast extraction system and one of its central elements is the kicker magnet. For the beam deflecting into the extraction septum-magnet it is supposed to use the nonferrous kicker magnet consisting of two couples of conductors. Recent changes made in configuration of the Booster extraction section demand decrease of the kicker magnet length that leads to change of the beam extraction scheme. This report is devoted to the choice of the alternative design of the magnet (the nonsymmetrical variant).

    JINR/VBLHEP, Dubna, Moscow region, Russia
  
  The calculation results of the gold ions beam losses along the Nuclotron Booster perimeter are given. The presented results take the ion stimulated desorption from the cold surface of the vacuum chamber and collimation of charge-exchanged gold ions into account.
