FAIR – MULTIPURPOSE HEAVY ION AND pbar FACILITY SIS100SIS300HESRFLAIRNESRRESR/CR • FAIR IS CONSIDERED AS INTERNATIONAL PROJECT • JINR IS INVOLVED IN the COLLABORATIVE WORK BASED ON AGREEMENTS, CONTRACTS AND PROJECTS SINCE 1999 A.Kovalenko 103 session of the JINR Scientific Council, Dubna, February 22, 2008
R&D DIRECTIONS: • SIS100 - fast-cycling superconducting synchrotron of the Nuclotron-type (LHE-group) • NESR – storage ring (LNP-group) A.Kovalenko 103 session of the JINR Scientific Council,Dubna, February 22, 2008
SIS100 COLLABORATIVE R&D : -MODEL DIPOLES & QUADRUPOLES; - FULL SIZE PROTOTYPES; - STEERERS AND MULTIPOLES;- LATTICE STRUCTURE OPTIMIZATION; - BEAM EXTRACTION and TRANSFER; - CLOSE ORBIT CORRECTION; - U(29+) COLLIMATION;- OTHER ELEMENTS: BPM, CATCHERS, ..; - CRYOSTAT MODULES; - COOLING SYSTEM; A.Kovalenko 103 session of the JINR Scientific Council,Dubna, February 22, 2008
JINR NUCLOTRON- prototype of the FAIR SIS100 synchrotron Nuclotron dipole and quadrupole magnets 34 T/m, 68 T/m s, quad 2 T, 4 T/s, 1 Hz dipole A.Kovalenko 103 session of the JINR Scientific Council,Dubna, February 22, 2008
NUCLOTRON SC - cable • NO OTHER CABLE WITH SIMILAR PARAMETERS Anatoly Alexeevich Smirnov ( 27.10.1930 – 10.02.2008) • Low degradation of the cable critical currentin a fast ramping operation (4.8 %. @ dB/dt=4T/s) • Weak dependence of the eddy current loss on the magnetic field ramp A.Kovalenko 103 session of the JINR Scientific Council,Dubna, February 22, 2008
SIS100 R&D at JINR:MODEL DIPOLES(1) Original Nuclotron dipole 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 EXEED1100000; • 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. costs study (GSI): nc version: 26M€ sc version: 2.6 M€ A.Kovalenko 103 session of the JINR Scientific Council,Dubna, February 22, 2008
SIS100 R&D at JINR:MODEL DIPOLES(2) Cold yoke 4.5 K Modified coil end-loops and new SC wire (4 mkm ) Modified yoke ends Stainless steel end plates and brackets Aperture 56 mm x 110 mm (v x h) Heat shield 80 K Basis for the first full length SIS100 prototype dipole A.Kovalenko 103 session of the JINR Scientific Council,Dubna, February 22, 2008
SIS100 R&D at JINR:MODEL QUADRUPOLES(1) AC LOSSES WERE REDUCED BY A FACTOR OF 3 SIS100 Maximum Quasi-continuous operation mode is possible also A.Kovalenko 103 session of the JINR Scientific Council,Dubna, February 22, 2008
