1 Plans for JINR participation at FAIR JINR Contributions: ● Accelerator Complex ● Condensed Baryonic Matter ● Antiproton Physics ● Spin Physics Physics Scope of FAIR: ● Accelerator Physics ● Nuclear Matter ● Physics with Antiprotons ● Applications

2 JINR participation in the accelerator part of the project

3 In 2000 –05 the JINR has developed and tested new prototypes of dipole and quadrupole magnets in which the heat release was about 2 times better than in the original ones. Total number of test cycles of these new prototypes exceeded Original Nuclotron dipole Performance of SC magnet with frequency 1 Hz

4 The full scale prototypes of SIS100 dipole and quadrupole magnets are at present under construction at JINR. Total structure of SIS100 includes: Dipoles Quadrupoles – 168 Estimated cost is about 15ME, including finishing the R&D. Dipole 2.75 м Quadrupole 1.1 м

5 Participation of JINR in the development of FAIR complex ( Facility for Antiproton and Ion Research ) PANDA (Proton ANtiproton DArmsdat): - Internal target PAX ( Polarized Antiproton eXperiment ) : - Polarization of antiprotons APR - proton-antiproton collisions NESR ( New Experimental Storage Ring ): - Electron ion collisions - Internal target FLAIR ( Facility for Low energy Antiproton Ion Research ): - Antihydrogen generation Participation of the group (lead by I.Meshkov) in the development of the numerical model for cooling and heating of the bean at the internal target and experimental study of these processes at COSY.

21 Conclusions The results presented above show strong participation of JINR groups in FAIR accelerator complex and experiments at FAIR In the most cases this participation is motivated by the unique expertise of JINR in the field of research and is highly appreciated by the Collaborations At the same time, participation of JINR groups in FAIR project increase this expertise and helps to develop the infrastructure which can be used for experiments at JINR basic facilities. In particular, the complementarities of FAIR and NICA provide the case for such collaboration
