Priority:

Status:

In-progress

Development of the JINR Basic Facility for Generation of Intense Heavy Ion and Polarized Nuclear Beams Aimed at Searching for the Mixed Phase of Nuclear Matter and Investigation of Polarization Phenomena at the Collision Energies up to = 9 GeV

Leaders:

A.N. Sissakian
A.S. Sorin
A.D. Kovalenko

Scientific Programme:
Investigation of the mixed phase formation problem in strongly interacting nuclear matter at extremely high nuclear densities and polarization phenomena in few-body nucleon systems. Development of theoretical models of the processes and theoretical support of the experiments. Development of the Nuclotron as the basis for study of relativistic nuclear collisions over atomic mass range A = 1 - 238. Preparation of the project of the nuclear collider and multipurpose particle detector at heavy ion colliding beams (NICA/MPD) and staged realization. Experiments at the Nuclotron nuclear and polarized deuteron beams.

Expected main results in 2008:

Final specification of necessary parameters of the accelerator complex and Multipurpose detector (MPD) for investigation of the mixed phase and other topical problems of the physics of relativistic hadrons, heavy ions and polarized particle interactions.
Progress on improvement the Nuclotron parameters within the frames of "Nuclotron-M" program including: improvement of vacuum in the beam pipe; optimization of the ion source KRION for generation of Au ⁵²⁺ and Xe ⁴⁴⁺ ions, work on the KRION-6 T. Development of a beam diagnostic system at the accelerator complex. Experiments at the Nuclotron beams on the first priority tasks of the accelerator development within the running time of 400 hours.
Start of the NICA facility realization including: design and optimization of the new linear pre-accelerator (q/A 0,14); preparation for the booster ring construction; R&D on the collider magnetic and beam cooling systems Design, construction and tests of the new model and prototype superconducting magnets with the maximum field up to 6 T for the NICA and the FAIR.
Simulation of the heavy ion collisions at various conditions will be developed in the framework of MPD ROOT shell. Necessary statistics will be generated and stored for further studies and usage by the Detector and Physics groups. The Letter of Intent part related to the Multipurpose Detector (MPD) will be completed. The wide R&D program for MPD sub-detectors will be started in order to complete the corresponding Technical Design Report by the end of 2009.
Experiments at the Nuclotron beams on the first priority tasks of physics and methodical experiments within the total running time of 800 hours.
