SIS100 COLLABORATIVE R&D :
•JINR NUCLOTRON- prototype of the FAIR SIS100 synchrotron
A.Kovalenko 103 session of the JINR Scientific Council ,Dubna, February 22, 2008
Nuclotron dipole and quadrupole magnets
2 T, 4 T/s, 1 Hz dipole 34 T/m, 68 T/m s, quad
Low degradation of thecable critical current in a
fast ramping operation(4.8 %. @ dB/dt=4T/s)
Anatoly Alexeevich Smirnov( 27.10.1930 – 10.02.2008)
•NUCLOTRON SC - cable
Weak dependence of the eddy current loss on the magnetic field ramp
NO OTHER CABLE WITH SIMILAR PARAMETERS

2001–2007: 23 TEST RUNS
4K YOKE DIPOLE: AC LOSSES WERE REDUCED BY A FACTOR OF 2 COMPARE TO THE NUCLOTRON
TOTAL NUMBER OF TEST CYCLES HAVE EXEED 1100000;
50K YOKE DIPOLE: COLD MASS OF THAT DIPOLE VERSION HAVE OPERATED 400 000 CYCLES
at B=2T, dB/dt=4T/s, f=1Hz. f FULL SIZE 4K YOKE DIPOLE EQUIVALENT – WAS PREPARED
AND TESTED.

• JINR FURTHER ACTIVE PARTICIPATION IN THE CONSTRUCTION OF THE SIS100 CRYOMAGNETIC SYSTEM WOULD BE VERY NATURAL • MANUFACTURING OF THE SIS100 MAGNETS AND OTHER LATTICE ELEMENTS (TS-2, TS-6,…) WOULD BE VALUABLE CONTRIBUTION OF RUSSIAN INDUSTRY AND LABORATORIES TO THE FAIR CONSTRUCTION
