A COMPACT 5 kN-TEST FACILITY FOR SUPERCONDUCTING CONDUCTORS CARRYING UP TO 1.5 kA IN MAGNETIC FIELDS UP TO 14 T

The variation of the critical current, Ic, in dependence on the applied strain, [MATH], is important for characterizing Nb3Sn superconducting wires. An apparatus for studying the strain sensitivity of Ic up to a magnetic field of 14 T under a mechanical load up to 5 kN and an electric current up to 1.5 kA is described. Some actual results for The variation of the critical current, Ic, in dependence on the applied strain, ε, is important for characterizing Nb3Sn superconducting wires. An apparatus for studying the strain sensitivity of Ic up to a magnetic field of 14 T under a mechanical load up to 5 kN and an electric current up to 1.5 kA is described. Some actual results for internally reinforced Nb3Sn conductors are presented.
