Superconducting Wires Transport

The laboratory provides characterization of superconducting wires, tapes and cables at low temperatures (2.7 – 77 K), external magnetic fields (0 – 12 T) and variable field orientations. Critical currents (I_c) of superconductors are measured by DC (up to 350 A) and by short (5 ms) pulse currents (up to 1500 A). The effect of bending (I_c(d)) and tensile stress (I_c(s) and I_c(e)) on the critical current degradation are also measured at 4.2 K and 77 K.

Equipment:

• Spilt-coil superconducting NbTi magnet (4.2 K, 0-8.5 T, all field orientation)
• Superconducting solenoid of inner bore 65 mm (4.2 K, 0-7T, perpendicular field)
• Cryogen-free superconducting magnet of inner bore 100 mm (4.2 and 77 K, 0-12T, perpendicular field)
• Low temperature tensile test instrument (60 mm sample, (4.2 and 77 K, up to 7 T)

Application:

• DC and pulsed IV characteristics of superconductors for estimation of critical current (I_c), n-exponent and quench power (thermal stability)
• Critical current degradation by bending (I_c(d)) and by tensile stress (s(e), I_c(s) and I_c(e))
