Abstract
An experimental apparatus for the research of the stress effects on superconducting wires has been developed. The apparatus is capable of loading tensile force up to one ton on a superconducting wire specimen with current up to 2000A under 5.5T magnetic field perpendicular to it at 4.2K.
Experimental results of critical current degradation of NbTi and Nb3Sn superconducting wires under tensile stress are presented. It is confirmed that Nb3Sn superconducting wire is more sensitive to tensile stress than NbTi superconducting wire.
A plan of the experiment hereafter is also described.
