1
JINR participation in the
accelerator part of the
project
2
Original Nuclotron dipole
•
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.
3
Performance of SC magnet with frequency 1 Hz
The full scale prototypes of SIS100 dipole and quadrupole magnets are
at present under construction at JINR.
Quadrupole 1.1 м
Dipole 2.75 м
Total structure of SIS100 includes:
Dipoles - 108
Quadrupoles – 168
Estimated cost is about 15ME, including finishing the R&D.

Participation of JINR in the development
of FAIR complex
(Facility for Antiproton and Ion Research)
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.
PAX (Polarized Antiproton eXperiment) :
- Polarization of antiprotons APR
- proton-antiproton collisions
PANDA (Proton ANtiproton DArmsdat):
- Internal target
FLAIR (Facility for Low energy
Antiproton Ion Research):
- Antihydrogen generation
NESR (New Experimental Storage Ring):
- Electron ion collisions

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
