FAIR Realisation – Superconducting Magnets Production StartE. Fischer∗, A. Bleile, E. Floch, W. Freisleben, V. Maroussov, F. Marzouki, H. Mu¨ller, J. P. Meier,A. Mierau, H. Raach, P. Schnizer, A.

TheuerkaufGSI, Darmstadt, GermanyIntroductionThe realisation phase of the pilot project of FAIR - theSIS100 synchrotron was started in January 2012, when themanufacturing contract for the dipole series was signedwith Babcock Noell. In parallel to the preparation for man-ufacturing the first dipole, urgent designed work was donefor the quadrupole and corrector magnets as well as plan-ning the cryogenic test facilities at GSI. The same work wasconcentrated on the Super Fragment Separator. In additionsignificant success was achieved in collaboration work bymanufacturing and testing a first SIS300 dipole model mag-net.Superconducting MagnetsRapidly-Cycling Magnets for SIS100Dipoles The design phase of a First of Series magnet(FoS) finished with the FDR in October 2012 and the pro-duction of the magnet has started with the manufacturingof the most critical component: the superconducting singlelayer coil (see Fig. 1). It will be ready for testing in spring2013. After a successful test of this first dipole the seriesproduction will start.Figure 1: Winding of a copper dummy-coil of the SIS100FoS dipoleQuadrupole Modules The SIS100 Quadrupole mod-ule contains two superconducting quadrupole magnets,corrector magnets and other devices such as BPM in thecommon quadrupole module cryostat [1, 2]. In the SIS100accelerator ring, 9 standard types and 3 special types (atthe injection, extraction and high radiation area), 84 mod-ules in total will be installed.The production of the module will be conducted as theGerman-Russian In-Kind contribution to FAIR. GSI will∗ e.fischer@gsi.deFigure 2: CAD Model of the cold mass of the SIS100quadrupole doublet module, type 3-F2, including suspen-sion system.provide the superconducting wires and the all devices ex-cept the magnets. The AC-losses and the hydraulic re-sistances were recalculated based on the final design ofthe magnet components [3, 4]. The mechanical stabilityof the QP-doublet modules versus thermal and mechanicalload was investigated. The assembly of the components,its mounting and operation procedure were analysed withFE models. The component stability during mounting wasinvestigating, together with the cold mass suspension andits stability at 4 K (see also Fig. 2). A first series doubletwill be build next, tested at JINR/Dubna and to be oper-ated at GSIs prototype test facility, and at a test string setup(dipole and quadrupole doublet module as minimum). Thefinal design of all different series SIS100 quadrupole dou-blet module types is actually under preparation. A tenderfor preparing CAD models to production plans is running,which will be based on the development results of the firstdoublet (type 3-F2).Rapidly-Cycling Magnets for SIS300The first prototype of a SIS300 curved dipole has beentested at INFN-LASA in Milan, Italy [7, 8]. At the mo-ment a second enhanced collared coil is built in frame ofthe European CRISP project. At IHEP in Protvino, Russia,a second SIS300 prototype quadrupole with enhanced lowloss cable is built and tested. (We acknowledge the supportof the European Community-Research Infrastructure Ac-tivity under the FP7 program CRISP [Grant agreement no:283745] Work Package 5). A first prototype of the steeringdipole is ready to be tested (see Fig. 3).Magnets for the Super-FRSSuperferric dipole The superferric dipoles are nolonger an In-Kind contribution from FAIR collaborationGSI SCIENTIFIC REPORT 2012 PHN-FAIR-13FAIR@GSI 237Figure 3: Insertion of the SIS300 prototype quadrupole intothe test cryostatpartners, but will be purchased via a FAIR call for ten-der. The necessary specifications are under preparation andshall be ready until summer 2013.Superconducting multiplets The superferric multi-plets are a GSI In-Kind contribution to the FAIR-Project.The specifications for the different magnets, as well as theintegrated modules are nearly finished and the call for ten-der is in preparation and will start in early 2013.Planning for TestingThe general testing strategy was defined this year:SIS100 dipoles will be tested in the now currently erectedseries test facility at GSI, SIS100 quadrupole units are fore-seen to be tested in collaboration with JINR and the Super-FRS magnet will be tested at CERN.Prototype Test Facility ActivitiesThe first SIS100 dipole magnet will be tested at the pro-totype test facility this year. So all required upgrade activ-ities were started last year in particular: a new power con-verter has been procured and new HTS current leads wereordered with their production already started.Series Test Facility ActivitiesThe SIS100 series test facility will be constructed inSH2/SH3 at GSI. In the hall, 3 test benches for the seriesproduction SIS100 dipole magnets and the string test facil-ity, which demonstrates the SIS100 accelerator construc-tion and the system operation, will be installed. For theinfrastructures such as power converters and cryo-plant, anutilitly building (SH5) will be errected. Necessary prepa-rations are ongoing with the commissioning of the facilityforeseen in the middle of 2014. Full scale tests will be start2014 and continue until 2017.Testing Super-FRS Magnets at CERNThe site of test was identified (building 180) and the in-frastructure is refurbished. The collaboration committeewill guide this process.Electrical Systems and Magnet ProtectionThe coil design and 3D quench calculations were contin-ued; both machines (SIS100 and SuperFRS) will use dumpresistors as protection devices with their preliminary val-ues defined. Bridge detectors for FAIR were successfullytested on a SIS100 dipole, and now the series is being ten-dered. For the SIS100 correctors special mutual inductancedetectors are foreseen and will be tested on the SIS100 sex-tupole magnet currently fabricated at JINR.The electrical safety systems for measuring insulationparameters for the SIS100 magnets are projected and shallbe developed together with collaboration partners. Paschentests were performed on the SIS100 prototype dipole per-formed in the range of 10−4 to 10−1 mBar. As the machineis not Paschen tight, appropriate interlocks are foreseen forthe cryostat vacuum system.ConclusionIn 2012 we achieved important results in preparing man-ufacturing and testing of the first fast ramped superconduct-ing magnets of the SIS100, the Super-FRS and the SIS300- core components of the FAIR project.References[1] E.
