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
