TLDR
In this paper, the influence of stresses/strains on critical current degradation in REBCO high-temperature superconducting (HTS) tapes wound onto a round cable were investigated.Abstract:
The influences of stresses/strains on critical current, I
c
in REBCO high-temperature superconducting (HTS) tapes wound onto a round cable were investigated. In the first step, the HTS tapes were helically wound on copper tubes with various diameters in the range of 2.95-8 mm. Considerably better results were achieved in case the superconducting layer was positioned during the winding at the inner side of the helix. The cables with tape wound on the tube with a diameter of 6.35 mm were subjected to bending tests with various bending radii in range from 21 to 60.5 mm. The I
c
degradation as a function of both the tube diameter and bending radius has been assessed from a current- voltage curve, from which the critical current was determined. The I, degradation in all samples was confirmed by microstructural investigation of an HTS layer by scanning electron microscopy.read more

Introduction of CORC®wires: highly flexible, round high-temperature superconducting wires for magnet and power transmission applications
Jeremy D Weiss,Tim Mulder,Tim Mulder,Herman H.J. ten Kate,Herman H.J. ten Kate,Danko van der Laan +5 more
TL;DR: In this article, a small 5-turn solenoid was constructed and measured as a function of applied magnetic field, exhibiting an engineering current density of 233 Amm−2 at 4.2 K and 10 T. Critical current measurements were performed on tapes extracted from CORC® wires made using 2 and 3 mm wide tape after bending the wires to various diameters from 10 to 3.5 cm.
