Description
For fusion superconductors in high magnet fields with currents in the order of 50 kA, single ReBCO coated conductors must be assembled in a cable geometry where combined torsion, axial and transverse loading states are anticipated in the tapes and tape joints. Axial and transverse loading, caused by differential thermal contraction and electromagnetic forces, may affect the transport properties. The effect of pre-applied twist on degradation of current carrying capability as a function of controlled tensile stress was studied at 77 K. Initial results of the effect of transverse pressure applied to tapes and lap joints. The transport properties and irreversibility limits are compared for pure axial tensile and compressive loading tests on free standing samples and when soldered to a Ti-alloy U-spring. An overview of the facilities and present results obtained on tapes from different manufacturers is given.
