  1. Cable and Strand test facility L. Oberli, A. Verweij Outline : • Test facilities installed in 103 and 163 • Cryogenic equipments to characterize the superconductors in 163 • Test program for coming years Workshop on test facilities

  2. Map of the Buildings 103 and 163 Control room Cold Box 130 l/h 163 Transpooling zone for cable Furnace Strand sample preparation area Preparation area for cable FRESCA Cryogenic Equipment in 163 : • 7 small Cryostats for strand tests • FRESCA facility for Ic cable test • 1 cold box • 6000 l dewar for Fresca operation 103 Workshop on test facilities

  3. Building 103 Strand and cable samples characterization “Chemical” room : Cu/Sc and metallography preparation Workshop on test facilities

  4. Building 163 Control room Cold Box 130 l/h RRR M Rc 163 Trans-spooling zone for cable Furnace Strand sample preparation area Preparation area for cable FRESCA Cryogenic Equipment in 163 : • 7 small cryostats for strand tests • FRESCA facility for Ic cable test • 1 cold box • 6000 l dewar for FRESCA operation LHe consumption : FRESCA ~ 70 % small crysotats ~ 30% 103 Workshop on test facilities

  5. 163 : Trans-spooling equipment and preparation area for strand samples Workshop on test facilities

  6. 163 : Cryogenic test facility for strand and cable samples 7 small cryostats for strand samples tests : • 2 cryostats for Ic on NbTi strand : 1 kA, B = 11 T at 4.2 K, 13 T at 1.9 K Sample holders for 10 samples • 1 cryostat for Ic test on Nb3Sn strand : 4 kA, B = 12.5 T at 4.2 K Sample holder for 2 kA and a single sample • 1 cryostat for thermal transfer measurements on insulated cable : 1.8 K < T < 2.1 K • 1 cryostat for Rc test on cable samples : 4.2 K • 1 cryostat for RRR test on NbTi and Nb3Snstrands • 1 cryostat for Magnetisation test on NbTi strands (to be upgraded to measure Nb3Sn strands and electromagnetic instabilities) Workshop on test facilities

  7. 163 : Test program for coming years Characterization of Nb3Sn strand byIc and RRR measurements for NED and CERN programs Ic measurements on LHC strands and on strands with very small filament diameter ( ~ 1 mm) Evaluation of the transfer of heat from the coil of the LHC dipole magnet to He II Rc test to qualify different types of coating for AC cables, tests on core cables and on LHC cables Magnetization measurements on LHC strands, Nb3Sn strands, strands for Neuro-spin project, strands for AC applications Workshop on test facilities
