  1. PLANS forJINRPARTICIPATION intheFAIR PROJECT: - ACCELERATOR TECHNOLOGY A.Kovalenko 103 session of the JINR Scientific Council,Dubna, February 22, 2008

  2. 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

  3. 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

  4. 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

  5. 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

  6. 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

  7. 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

  8. 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

  9. 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

  10. 103 session of the JINR Scientific Council,Dubna, February 22, 2008

  11. JINR’s EXPERIMENTAL WORKSHOPS • THE NUCLOTRON CRYO-MAGNETIC SYSTEM WAS MANUFACTURED HERE A.Kovalenko 103 session of the JINR Scientific Council,Dubna, February 22, 2008

  12. FULL SIZE SIS100 DIPOLE & QUAD (1) • YOKE MANUFACTURING AT JINR EW EU PROJECT: DIRACSecondary beams N515873 A.Kovalenko 103 session of the JINR Scientific Council,Dubna, February 22, 2008

  13. FULL SIZE SIS100 DIPOLE & QUAD(2) • COLE MANUFACTURING AT LHE EU PROJECT: DIRACSecondary beams N515873 A.Kovalenko 103 session of the JINR Scientific Council,Dubna, February 22, 2008

  14. JINR PROPOSAL ESTIMATED COST ~ 35 Meuro,( less than 30% of the proposed Russian contribution to FAIR) A.Kovalenko 103 session of the JINR Scientific Council,Dubna, February 22, 2008

  15. FAIR WORK PACKAGES A.Kovalenko 103 session of the JINR Scientific Council,Dubna, February 22, 2008

  16. 2nd Lab Directors Meeting, Protvino, January 15/16, 2008 Lab Directors Meeting, Darmstadt, October1/2, 2007 A.Kovalenko

  17. 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 BEVALUABLE CONTRIBUTION OF RUSSIAN INDUSTRY AND LABORATORIES TO THE FAIR CONSTRUCTION A.Kovalenko 103 session of the JINR Scientific Council,Dubna, February 22, 2008
