Abstract :
A Bi-2212 cable-in-conduit featuring incorporated stress management is being developed. By using a compliant thin wall tube made of Inconel X 750 in the center of the CIC the strands of the cable are protected from the accumulated Lorentz stress. This significantly reduces the mechanical loading on the superconductor while it is still being held rigidly in place. A finite element analysis of a cable matrix is presented, and mechanical tests of the Inconel X 750 tubes are shown.
