• 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 1 400 000.

The full scale prototypes of SIS100 dipole and quadrupole magnets are at present under construction at JINR.

Total structure of SIS100 includes: Dipoles - 108 Quadrupoles – 168 Estimated cost is about 15ME, including finishing the R&D.

Dipole 2.75 м Quadrupole 1.1 м

Project PAX

PAX represents very interesting possible extension of FAIR. Namely, to have polarized antiproton beam and, ultimately, to have collider mode for polarized protons and antiprotons.

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
