MAgnete per RIcerca Superconduttività Applicata – MaRiSA
Test of critical current of high current superconducting cable up to 8T in a bore up to 440 mm and current up to 100 kA with a transformer method.
Technical Means:
• Magnetic Field of 8T in 330 mm bore with sample temperature 1K<T<300 K;
• Magnetic Field of 6T in 440 mm with temperature 1K<T<300 K;
• Sample shaped as a ring with low resistance joint;
• Maximum current 100 kA.
Among the most significant results, critical current measurements of:
• 30 conductors used for HERA superconducting dipoles
• All conductors (6) involved in BaBar Superconducting Solenoid (SLAC)
• All conductors (20) involved in CMS Superconducting Solenoid (CERN)
• All conductor involved in Mu2e superconducting solenoids (43 tests)
Technical steps and expertise:
• Construction of a sample holder according the specific requirements, equipped with Cernox thermometers and Hall probes,
• Cool-down of the magnet (1500 l ol LN2 and 1000 l of LHe for one measurement run),
• Check-up of the Magnet Safety System (MSS),
• Securing the area,
• Magnetic field rise
• Tests on the sample.
