  3. Preparation of FAIR Construction Side Civil construction and procurement of major accelerator components and series has started

  4. Major Accelerator Procurements Started

  5. Integrated Project Tools • Definition of a frame schedule for the subprojects and the major procurements. • Setting-up of a MS project based, detailed time schedule for each machine and work • package. • Definition of work package leaders. • Goal: Meeting the official milestones „building readiness“ for all components needed for the comissioning with beam. For SIS100 and HEBT primary beam lines: 2016. • Planning and estimate of (human resources) and the cross support of the project devisions • Identification of (time) critical components (long lead items) and setting of priorities. • Consideration of interconnection and links of the subprojects. • Integration of budget profiles. • Final goal: Tool for the follow-up of the subprojects, the busget flow and the resource • management.

  12. Preparing the Injector Chain – UNILAC upgrade Exchange of 35 years old Alverez accelerator With modern interdigital H-type structures Higher intensities  28 GHz ECRIS • SIS 18 upgrade • Fast ramping, enhanced intensity • per pulse • Increase of injection acceptance • Improvement of lifetime for low-charged U-ions • Increase of beam-intensity per time due to reduction of SIS18- cycle time • UNILAC upgrade • High power (high intensity), • short pulses • Increase of beam brilliance (Beam current / emittance) • Increase of transported beam currents • Improvements of high current beam diagnostics / operation

  13. Preparing the Injector Chain - SIS18 Upgrade Scrapers and NEG coating for pressure stabilization Injection system for low charged state heavy ions Charge separator for higher intensity and high quality beams h=2 acceleration cavity for faster ramping Power grid connection The SIS18upgrade program: Booster operation with intermediate charge state heavy ions

  17. Status of Major Procurements • Status Procurements: • SIS100 dipole modules: contract signed, FDR completed, preseries magnet in production • SIS100 quadrupole modules preseries (including all components): Detailed design(at GSI) and specifications close to be completed • SIS100 quadrupole module series: Tendering process of module design running • Power converter upgrade for s.c. magnet test stand (20 kA): in production • High current HTS current leads (for test stand and option for series): type 1 in production • Sc. wire (all s.c. SIS100 magnets): ordered • SIS100 dipole magnet chambers: contract signed – production running • SIS18 h=2 acceleration cavity: Test of first module in January, installation in May 2013 - Remaining procurements in Q1 2013 • SIS18 main dipole power converter upgrade: Contract signed – production running • SIS18 correction coils PC: production running • Main specifications (long lead items) • SIS100 acceleration system: spec completed (transfered to FAIR) – tendering in preparation • SIS100 bunch compression systems: specs. completed – procurement in preparation • HEBT nc magnets (incl. chambers and support) batch 1: specifications completed (transferred to FAIR) inkind contract in preparation – UHV system components signed • HEBT nc magnets batch 2 and 3: specification almost completed • SIS100 dipole series test stands cryogenics plant and local cryogenics: contract singned • Next main goal: Completion of design and specifications for the preseries SIS100 quadrupole module, including all components until end of March • Completion of Specifications for local cryogenics components

  18. S.C. Magnet Testing • SIS100 dipole units will be tested at GSI • SIS100 quadrupole units potentially tested at JINR • Super-FRS magnets potentially tested at CERN • Since the testing is strongly linked to the magnet production – all missing decisions must be taken soon. • For the SIS100 dipole testing and the SIS100 string test, an existing large building plus annex buildings are prepared. SIS300 magnet testing has been considered as later option. • Major procurements are launched (e.g. cryogenic plant and feed boxes)

  19. Upgrade GSI Magnet Teststand • 20 kA upgrade of the test facility at GSI in preparation • Power converter upgrade contracted • New HTS current leads contracted

  20. Interaction with Civil Engineering • Room specific data (temperature tolerance, humidity..) • Cable data for cable routing and cable trays • Component data (in the supply areas) • Planning of suppy areas in detail • Full integration of infrastructure and collision checks • Input for radioprotection/shielding design • Next civil construction milestones in 2013: • Construction of building pillars • Preparation of construction side 20

  21. SIS300 System Design (not part of Module 0-3) • Major improvements of the lattice/optics design in 2012. • Significantly improved performance of slow extraction at high energies • by means of a new sextupole arrangement • Open System Design Issues: • Slow extraction of large emittance beams, e.g. low energy beams, stretcher mode • Is transverse coupling an option to reduce the horizontal beam size ? • Operation with low charge state beams with major ionization beam loss. • Is protection of the magnets in the extraction straight possible ? • Is the amount of ionization beam loss in the arcs low enough to avoid quenching ?

  22. SIS300–SIS100 Synergies of Components

  23. SIS300 Dipole Magnet (INFN) Full length curved, fast ramped s.c. SIS300 dipole magnet Preparation for testing at LASA Curved winding of a collared low loss cable

  24. Results of SIS300 Dipole Magnet Testing • The SIS-300 model magnet DISCORAP reached the nominal current with only one training quench. • The magnet has been operated in pulsed regime, up to dB0/dt = 0.7 T/s (the upper limit of the station). • The magnet has demonstrated to work in fast ramp rate up to the ultimate field (B0=4.5 T) with some limitations. • The main evident limitation is that the maximum variation of field allowed ΔB0=1.5 T - 2 T for fast ramp rate, independently by the final field or to the sign of the ramp. • Preliminary results show that the losses are very low (at least a factor 2 below the estimated value, even if the region at the nominal ramp rate has not been already explored).

  25. SIS300 Magnets – CRISP Program Development and manufacturing of an upgraded collared coil of a SIS300 type dipole with An enhanced 2d-coil block design to minimize field errors A better design of the coil ends, also to reduce field errors A new low loss conductor (Bruker EST wire) A full (second) magnet could be build if additional money is available

  26. SIS300 Magnets – 2nd Generation s.c. Dipole Wire INFN money CERN EU-money: Cable production Tests on insulation scheme INFN EU-money: Modify Coil design Provide Material for Collars, End spacers, Coil wedges, Coil protection sheaths. GSI EU-money: Project coordination Cable Manpower costs ARD money ASG Drawings of coil Manufacturing drawings (for end spacers, wedges, tools etc.) Assembly of tools Construction of coils Assembly of collared coil Q.A. and tests Materials

  27. SIS300 Quadrupole Magnet (IHEP)

  28. Results of Quadrupole Testing at IHEP Two SIS300 quadrupole prototypes were manufactured and successfully tested. The nominal central gradient of 45 T/m with ramp rate of 10 T/m/s was produced by a single - layer coil at 6.25 kA current. 8.7 and 9.4 kА critical current (40 and 50 % current margin) were reached in 1st and 2nd prototypes. The critical current of the quadrupoles was higher than 8.5 kA up to 5 kA/s (36 T/m/s, 2.8 T/s) ramp rate. Hysteresis AC losses of the second prototype is lower than the first that by factor 1.5 up to 3 kA current and 1.06 at 5 kA. The lower harmonic components of the quadrupole magnetic field at 3 kA current were less than 2×10-4 which is an acceptable level.
